Organocatalytic Asymmetric N-Sulfonyl Amide C-N Bond Activation to Access Axially Chiral Biaryl Amino Acids
ARTICLE https://doi.org/10.1038/s41467-020-14799-8 OPEN Organocatalytic asymmetric N-sulfonyl amide C-N bond activation to access axially chiral biaryl amino acids Guanjie Wang1, Qianqian Shi2, Wanyao Hu1, Tao Chen1, Yingying Guo1, Zhouli Hu1, Minghua Gong1, ✉ ✉ ✉ Jingcheng Guo1, Donghui Wei 2 , Zhenqian Fu 1,3 & Wei Huang1,3 1234567890():,; Amides are among the most fundamental functional groups and essential structural units, widely used in chemistry, biochemistry and material science. Amide synthesis and trans- formations is a topic of continuous interest in organic chemistry. However, direct catalytic asymmetric activation of amide C-N bonds still remains a long-standing challenge due to high stability of amide linkages. Herein, we describe an organocatalytic asymmetric amide C-N bonds cleavage of N-sulfonyl biaryl lactams under mild conditions, developing a general and practical method for atroposelective construction of axially chiral biaryl amino acids. A structurally diverse set of axially chiral biaryl amino acids are obtained in high yields with excellent enantioselectivities. Moreover, a variety of axially chiral unsymmetrical biaryl organocatalysts are efficiently constructed from the resulting axially chiral biaryl amino acids by our present strategy, and show competitive outcomes in asymmetric reactions. 1 Key Laboratory of Flexible Electronics & Institute of Advanced Materials, Jiangsu National Synergetic Innovation Center for Advanced Materials, Nanjing Tech University, 30 South Puzhu Road, Nanjing 211816, China. 2 College -

Reliable Determination of Amidicity in Acyclic Amides and Lactams Stephen A
Article pubs.acs.org/joc Reliable Determination of Amidicity in Acyclic Amides and Lactams Stephen A. Glover* and Adam A. Rosser Department of Chemistry, School of Science and Technology, University of New England, Armidale, NSW 2351, Australia *S Supporting Information ABSTRACT: Two independent computational methods have been used for determination of amide resonance stabilization and amidicities relative to N,N-dimethylacetamide for a wide range of acyclic and cyclic amides. The first method utilizes carbonyl substitution nitrogen atom replacement (COSNAR). The second, new approach involves determination of the difference in amide resonance between N,N-dimethylacetamide and the target amide using an isodesmic trans-amidation process and is calibrated relative to 1-aza-2-adamantanone with zero amidicity and N,N-dimethylace- tamide with 100% amidicity. Results indicate excellent coherence between the methods, which must be regarded as more reliable than a recently reported approach to amidicities based upon enthalpies of hydrogenation. Data for acyclic planar and twisted amides are predictable on the basis of the degrees of pyramidalization at nitrogen and twisting about the C−N bonds. Monocyclic lactams are predicted to have amidicities at least as high as N,N-dimethylacetamide, and the β-lactam system is planar with greater amide resonance than that of N,N- dimethylacetamide. Bicyclic penam/em and cepham/em scaffolds lose some amidicity in line with the degree of strain-induced pyramidalization at the bridgehead nitrogen and twist about the amide bond, but the most puckered penem system still retains substantial amidicity equivalent to 73% that of N,N-dimethylacetamide. ■ INTRODUCTION completed by a third resonance form, III, with no C−N pi Amide linkages are ubiquitous in proteins, peptides, and natural character and on account of positive polarity at carbon and the or synthetic molecules and in most of these they possess, electronegativity of nitrogen, must be destabilizing. -

Experiment 8 Thermochemistry This Week In
Experiment 8 Thermochemistry CH 204 Fall 2006 Dr. Brian Anderson What is Thermochemistry? The study of heat in chemical reactions. Forming chemical bonds releases energy. Breaking chemical bonds requires energy. How much energy? Depends on the bond. Add up all the energies to get the heat of reaction, ∆Hrxn . This week in lab We will measure the amount of heat given off by 50 ml of hot water, by some chunks of hot metal, and by two chemical reactions + 2+ Mg + 2H → Mg + H2 + heat + 2+ MgO + 2H → Mg + H2 O + heat We’ll do all these reactions in a coffee cup calorimeter. 1 The basic operation of calorimetry - Start with a known volume of a solution in the calorimeter. - Drop in something hot, or start a reaction that generates heat. - Close the calorimeter and measure the increase in temperature as heat is generated. - Keep measuring the temperature until it finally levels out. Part One: Add hot water to cold 50 mL of cold water (5ºC). Add 50 mL of hot water (75ºC). Final temp should be (75 + 5) ÷ 2 = 40ºC But the final temp will actually be lower than that because the cup itself will absorb a little bit of the heat. Heat Capacity We will use the data in part 1 to calculate the heat capacity of the cup, in units of J/K. This will tell us how many Joules of heat the cup absorbs for every K (or degree C) the water heats up. We know how many Joules of heat we added with the hot water, and we can calculate how many Joules were absorbed by the cold water as it warmed up. -
Oxide Fuel Cells with Hydrocarbon and Syngas Fuels—A Review
Fundamentals of electro- and thermochemistry in the anode of solid- oxide fuel cells with hydrocarbon and syngas fuels—a review Jeffrey Hanna,∗a Won Yong Lee,a Yixiang Shi,b and Ahmed F. Ghoniema Received Xth XXXXXXXXXX 20XX, Accepted Xth XXXXXXXXX 20XX First published on the web Xth XXXXXXXXXX 200X DOI: 10.1039/b000000x High fuel flexibility of solid-oxide fuel cells (SOFCs) affords the possibility to use relatively cheap, safe, and readily available hydrocarbon (e.g., CH4) or coal syngas (i.e., CO-H2 mixtures) fuels. Utilization of such fuels would greatly lower fuel cost and in- crease the feasibility of SOFC commercialization, especially for near-term adoption in anticipation of the long-awaited so-called “hydrogen economy.” Current SOFC technology has shown good performance with a wide range of hydrocarbon and syngas fu- els, but there are still significant challenges for practical application. In this paper, the basic operating principles, state-of-the-art performance benchmarks, and SOFC-relevant materials are summarized. More in-depth reviews on those topics can be found in Kee and co-workers [Combust. Sci. and Tech., 2008, 180, 1207–1244 and Proc. Combust. Inst., 2005, 30, 2379–2404] and McIntosh and Gorte [Chem. Rev., 2004, 104, 4845–4865]. The focus of this review is on the fundamentals and development of detailed electro- and thermal (or simply, electrothermal) chemistry within the SOFC anode, including electrochemical oxidation mechanisms for H2, CO, CH4, and carbon, as well as the effects of carbon deposition and sulfur poisoning. The interdependence of heterogeneous chemistry, charge-transfer processes, and transport are discussed in the context of SOFC-membrane-electrode assembly (MEA) modeling.
