Rhodium-Catalyzed Synthesis of Organosulfur Compounds Involving S-S Bond Cleavage of Disulfides and Sulfur
molecules Review Rhodium-Catalyzed Synthesis of Organosulfur Compounds Involving S-S Bond Cleavage of Disulfides and Sulfur Mieko Arisawa * and Masahiko Yamaguchi Department of Organic Chemistry, Graduate School of Pharmaceutical Sciences, Tohoku University, Aoba, Sendai 980-8578, Japan; [email protected] * Correspondence: [email protected]; Tel.: +81-22-795-6814 Academic Editor: Bartolo Gabriele Received: 17 July 2020; Accepted: 5 August 2020; Published: 7 August 2020 Abstract: Organosulfur compounds are widely used for the manufacture of drugs and materials, and their synthesis in general conventionally employs nucleophilic substitution reactions of thiolate anions formed from thiols and bases. To synthesize advanced functional organosulfur compounds, development of novel synthetic methods is an important task. We have been studying the synthesis of organosulfur compounds by transition-metal catalysis using disulfides and sulfur, which are easier to handle and less odiferous than thiols. In this article, we describe our development that rhodium complexes efficiently catalyze the cleavage of S-S bonds and transfer organothio groups to organic compounds, which provide diverse organosulfur compounds. The synthesis does not require use of bases or organometallic reagents; furthermore, it is reversible, involving chemical equilibria and interconversion reactions. Keywords: rhodium; catalysis; synthesis; organosulfur compounds; S-S bond cleavage; chemical equilibrium; reversible reaction 1. Introduction 1.1. Structure and Reactivity of Organic Disulfides Organosulfur compounds containing C-S bonds are widely used for the manufacture of drugs and materials. Compared with organic compounds containing oxygen, which is another group 16(6A) element, different properties appear owing to the large size and polarizability of sulfur atoms. -

Heterocyclic Chemistry Updated
1 | Page Heterocyclic Chemistry By Dr Vipul Kataria Definition: A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements (N, O, S, P) as members of its ring. Introduction: Heterocyclic compounds may be defined as cyclic compounds having as ring members atoms of at least two different elements. It means the cyclic compound has one another atom different than carbon. Heterocyclic compounds have much importance in organic chemistry because of abundant presence of heterocyclic compounds in present pharmaceutical drugs. Like other organic compounds, there are several defined rules for naming heterocyclic compounds. IUPAC rules for nomenclature of heterocyclic systems (SPU 2012, 2 Marks) The system for nomenclature for heterocyclic systems was given by Hantzsch and Widman. The Hantzsch-Widman nomenclature is based on the type (Z) of the heteroatom; the ring size (n) and nature of the ring, whether it is saturated or unsaturated. This system of nomenclature applies to monocyclic 3-to-10-membered ring heterocycles. Type of the heteroatom: The type of heteroatom is indicated by a prefix as shown below for common hetreroatoms. Dr Vipul Kataria, Chemistry Department, V. P. & R. P. T. P. Science College, VV Nagar 2 | Pag e When two or more of the same heteroatoms are present, the prrefix di, tri, tetra… are used. e.g. dioxa, triaza, dithia. If the heteroatoms are different their atomic number in that grroup is considered. Thus order of numbering will be O, S, N, P, Si. Ring size: The ring size is indicated by a suffix according to Table I below. -

Heterocyclic Compound –A Review
IOSR Journal of Applied Chemistry (IOSR-JAC) ISSN: 2278-5736, PP 43-46 www.iosrjournals.org Heterocyclic Compound –A Review Shital V. Hote 1, Shital P. Bhoyar2 1, 2 Department of Applied Chemistry, Shri Datta Meghe Polytechnic, Nagpur, India ABSTRACT : Main aim of this paper is to present the information regarding the Heterocyclic compounds that constitute the largest family of organic compounds. These are extremely important with wide array of synthetic, pharmaceutical and industrial applications. There is always a strong need for new and efficient processes in synthesizing of new Heterocycles. Several 1,3,4,5-tetraaryl-2 pyrazoline, 41 –piperazine, 3- methoxybenzofuran and thiazolidin-4-one substituted 1, 2, 4-triazole, 4- NO2, 2-OH and 4-Cl in phenyl ring at 5- position of pyrazoline ring of synthesized compounds. The new compounds were characterized using IR, 1H-NMR, 13C-NMR and mass spectra. Biological screening of some compounds is reported. Keywords: Synthesized compounds, heterocyclic substances. I. INTRODUCTION Compounds classified as heterocyclic probably constitute the largest and most varied family of organic compounds. After all, every carbocyclic compound, regardless of structure and functionality, may in principle be converted into a collection of heterocyclic analogs by replacing one or more of the ring carbon atoms with a different element. Even if we restrict our consideration to oxygen, nitrogen and sulfur (the most common heterocyclic elements), the permutations and combinations of such a replacement are numerous. Derivatives of the simple fused ring heterocycle purine constitute an especially important and abundant family of natural products. The amino compounds adenine and guanine are two of the complementary bases that are essential components of DNA. -

Yousef, Saad A.Al-Tamrah, Basmah H. Al-Shammari 4 3 Abstract— Indole is an aromatic heterocyclic organic 5 compound. The indole nucleus is very important for many 2 6 N N + N1 natural and synthetic molecules with significant biological 7 H H activity. Compounds that contain an indole ring are called H indoles. Indoles are an important class of heterocycles not only Indole Canonical because they are among the most ubiquitous compounds in nature, but also because they have a wide range of biological Indole, a secondary amine, is a natural product of pancreatic activities. 2,4,6-Trimethoxybenzaldehyde can be used as digestion, bacterial action and putrefaction decomposition. antibacterial synergist. When indole was mixed with Indole is the precursor to many pharmaceuticals. The name 2,4,6-trimethoxybenzaldehyde at room temperature, no color indole is portmanteau of the words indigo and oleum, since was observed. However in the presence of concentrated indole was first isolated by treatment of the indigo dye with hydrochloric acid, a brown red complex is formed which has a oleum. Indole chemistry began with the study of the dye maximum absorbance at 488 nm. The parameters affecting this indigo. The indole ring is also found in many natural products reaction were studied in order to find the suitable conditions for such as the vinca alkaloids, fungal metabolites and marine the reaction to complete.
