INTRODUCTION. Vitamin B-12 otherwise known as cyanocobalamin is a compound with synthetic elegance. Considering how it is composed of an aromatic macrocyclic corrin there are key features of this molecule that are observed either in its synthesis of in the biochemical reactions it plays a role in whether they be isomerization reactions or transfer reactions. In this paper the focus for the discussion will be on the history, chemical significance and total synthesis of vitamin B12. Even more so the paper will be concentrated one of the two variants of the vitamin B-12 synthesis, namely the ETH Zurich variant spearheaded by Albert Eschenmoser.Examining the structure as a whole it is observed that a large portion of the vitamin B12 is a corrin structure with a cobalt ion in the center of the macrocyclic part, and that same cobalt ion has cyanide ligands.

  • Rare-Earth Metal Methylidene Complexes with Ln3 (Μ3-CH2)(Μ3
    Dalton Transactions View Article Online PAPER View Journal | View Issue Rare-earth metal methylidene complexes with Ln3(μ3-CH2)(μ3-Me)(μ2-Me)3 core structure† Cite this: Dalton Trans., 2015, 44, 18101 Dorothea Schädle,a Melanie Meermann-Zimmermann,b Cäcilia Maichle-Mössmer,a Christoph Schädle,a Karl W. Törnroosc and Reiner Anwander*a Trinuclear rare-earth metal methylidene complexes with a Ln3(µ3-CH2)(µ3-Me)(µ2-Me)3 structural motif were synthesized by applying three protocols. Polymeric [LuMe3]n (1-Lu) reacts with the sterically demand- ing amine H[NSiMe3(Ar)] (Ar = C6H3iPr2-2,6) in tetrahydrofuran via methane elimination to afford isolable monomeric [NSiMe3(Ar)]LuMe2(thf)2 (4-Lu). The formation of trinuclear rare-earth metal tetramethyl methylidene complexes [NSiMe3(Ar)]3Ln3(µ3-CH2)(µ3-Me)(µ2-Me)3(thf)3 (7-Ln; Ln = Y, Ho, Lu) via reaction of [LnMe3]n (1-Ln; Ln = Y, Ho, Lu) with H[NSiMe3(Ar)] is proposed to occur via an “intermediate” species of the type [NSiMe3(Ar)]LnMe2(thf)x and subsequent C−H bond activation. Applying Lappert’s concept of Lewis base-induced methylaluminate cleavage, compounds [NSiMe3(Ar)]Ln(AlMe4)2 (5-Ln; Ln = Y, La, Nd, Creative Commons Attribution-NonCommercial 3.0 Unported Licence. Ho) were converted into methylidene complexes 7-Ln (Ln = Y, Nd, Ho) in the presence of tetrahydrofuran. Similarly, tetramethylgallate complex [NSiMe3(Ar)]Y(GaMe4)2 (6-Y) could be employed as a synthesis pre- cursor for 7-Y. The molecular composition of complexes 4-Ln, 5-Ln, 6-Y and 7-Ln was confirmed by elemental analyses, FTIR spectroscopy, 1H and 13C NMR spectroscopy (except for holmium derivatives) Received 30th July 2015, and single-crystal X-ray diffraction.

  • Solving the Schrödinger Equation for Helium Atom and Its Isoelectronic
    THE JOURNAL OF CHEMICAL PHYSICS 127, 224104 ͑2007͒ Solving the Schrödinger equation for helium atom and its isoelectronic ions with the free iterative complement interaction „ICI… method ͒ Hiroyuki Nakashima and Hiroshi Nakatsujia Quantum Chemistry Research Institute, Kyodai Katsura Venture Plaza 106, Goryo Oohara 1-36, Nishikyo-ku, Kyoto 615-8245, Japan and Department of Synthetic Chemistry and Biological Chemistry, Graduate School of Engineering, Kyoto University, Nishikyo-ku, Kyoto 615-8510, Japan ͑Received 31 July 2007; accepted 2 October 2007; published online 11 December 2007͒ The Schrödinger equation was solved very accurately for helium atom and its isoelectronic ions ͑Z=1–10͒ with the free iterative complement interaction ͑ICI͒ method followed by the variational principle. We obtained highly accurate wave functions and energies of helium atom and its isoelectronic ions. For helium, the calculated energy was −2.903 724 377 034 119 598 311 159 245 194 404 446 696 905 37 a.u., correct over 40 digit accuracy, and for H−,itwas−0.527 751 016 544 377 196 590 814 566 747 511 383 045 02 a.u. These results prove numerically that with the free ICI method, we can calculate the solutions of the Schrödinger equation as accurately as one desires. We examined several types of scaling function g ␺ and initial function 0 of the free ICI method. The performance was good when logarithm functions were used in the initial function because the logarithm function is physically essential for three-particle collision area. The best performance was obtained when we introduce a new logarithm function containing not only r1 and r2 but also r12 in the same logarithm function.

  • Many-Electron System I – Helium Atom and Pauli Exclusion Principle
    Lecture 17 Many-electron System I { Helium Atom and Pauli Exclusion Principle Study Goal of This Lecture • Helium atom - many electron wavefunctions • Helium atom - variational ground state (screening) • Eigenstates of a two-spin system 17.1 Helium Atom Helium atom includes two electrons moving around a fixed nucleus with charge Z = 2, we can write down the Hamiltonian as: 2 2 2 2 ^ ~ 2 2 1 Ze Ze e H = − (r1 + r2) − ( + − ) 2me 4π0 r1 r2 r12 2 2 2 2 2 ~ 2 1 Ze ~ 2 1 Ze e = − r1 − − − r2 − + 2me 4π0 r1 2me 4π0 r2 4π0r12 (17.1) | {z } | {z } | {z } H^1 H^2 H^12 = H^1 + H^2 + H^12: 1 If H^12 = 0(or neglected) then the problem is exactly solved. Recall that for a total system composes of independent sub-systems H^T = H^1 + H^2 + ··· ; (17.2) and we can firstly solve all ^ n n n Hnφm = Emφm; (17.3) then the solution of H^T is the product states Y n = φ : (17.4) n If consider as many-electrons, i.e. H^n for the n-th electron. Then the product solu- tion is a natural "independent electron" solution. Even when the electron-electron interactions are non-zero, we will see the independent electorn approximation is a good starting point. Let's consider the Helium atom, we know: H^1φ1 = E1φ1; (17.5) H^2φ2 = E2φ2; and total E = E1 + E2. φ1; φ2 are Helium hydrogen-like atomic orbitals. We know the two ground states (neglect spin for a moment.) H^1φ1s(1) = E1sφ1s(1); (17.6) H^2φ1s(2) = E1sφ1s(2); number 1 and 2 denotes electorn 1 and electron 2 respectively.

Spermine oxidase (SMOX) is the key and most recently discovered enzyme of polyamine metabolism that plays an es- sential role in regulating polyamine homeostasis by catalyzing the back-conversion of Spm to Spd. The deve- lopment of many types of epithelial cancer is associated with inflammation, and disease-related inflammatory stimuli induce SMOX. MDL72527 is widely used in vitro and in vivo as an irreversible inhibitor of SMOX, but it is also potent towards N1-acetylpolyamine oxidase. Although SMOX has high substrate specificity, Spm analogues have not been systematically studied as enzyme inhibitors.

  • Designing Universal Chemical Markup (UCM) Through the Reusable Methodology Based on Analyzing Existing Related Formats
    Designing Universal Chemical Markup (UCM) through the reusable methodology based on analyzing existing related formats Background: In order to design concepts for a new general-purpose chemical format we analyzed the strengths and weaknesses of current formats for common chemical data. While the new format is discussed more in the next article, here we describe our software s t tools and two stage analysis procedure that supplied the necessary information for the n i r development. The chemical formats analyzed in both stages were: CDX, CDXML, CML, P CTfile and XDfile. In addition the following formats were included in the first stage only: e r P CIF, InChI, NCBI ASN.1, NCBI XML, PDB, PDBx/mmCIF, PDBML, SMILES, SLN and Mol2. Results: A two stage analysis process devised for both XML (Extensible Markup Language) and non-XML formats enabled us to verify if and how potential advantages of XML are utilized in the widely used general-purpose chemical formats. In the first stage we accumulated information about analyzed formats and selected the formats with the most general-purpose chemical functionality for the second stage. During the second stage our set of software quality requirements was used to assess the benefits and issues of selected formats. Additionally, the detailed analysis of XML formats structure in the second stage helped us to identify concepts in those formats. Using these concepts we came up with the concise structure for a new chemical format, which is designed to provide precise built-in validation capabilities and aims to avoid the potential issues of analyzed formats.

  • Linking Nwchem and Avogadro with the Syntax and Semantics of Chemical Markup Language Wibe a De Jong1*†, Andrew M Walker2† and Marcus D Hanwell3†
    de Jong et al. Journal of Cheminformatics 2013, 5:25 http://www.jcheminf.com/content/5/1/25 RESEARCH ARTICLE Open Access From data to analysis: linking NWChem and Avogadro with the syntax and semantics of Chemical Markup Language Wibe A de Jong1*†, Andrew M Walker2† and Marcus D Hanwell3† Abstract Background: Multidisciplinary integrated research requires the ability to couple the diverse sets of data obtained from a range of complex experiments and computer simulations. Integrating data requires semantically rich information. In this paper an end-to-end use of semantically rich data in computational chemistry is demonstrated utilizing the Chemical Markup Language (CML) framework. Semantically rich data is generated by the NWChem computational chemistry software with the FoX library and utilized by the Avogadro molecular editor for analysis and visualization. Results: The NWChem computational chemistry software has been modified and coupled to the FoX library to write CML compliant XML data files. The FoX library was expanded to represent the lexical input files and molecular orbitals used by the computational chemistry software. Draft dictionary entries and a format for molecular orbitals within CML CompChem were developed. The Avogadro application was extended to read in CML data, and display molecular geometry and electronic structure in the GUI allowing for an end-to-end solution where Avogadro can create input structures, generate input files, NWChem can run the calculation and Avogadro can then read in and analyse the CML output produced. The developments outlined in this paper will be made available in future releases of NWChem, FoX, and Avogadro. Conclusions: The production of CML compliant XML files for computational chemistry software such as NWChem can be accomplished relatively easily using the FoX library.
