paper, a simple method is introduced for the synthesis of novel 4‐substituted‐3‐thioxo‐3,4‐dihydrobenzo[e][1,3]thiazepin‐5(1H)‐one derivatives. The synthesis is based on a two‐step reaction of 2‐methylbenzoic acid, an amine, and carbon disulfide. In the first step, 2‐methylbenzoic acid reacts with sulfuric acid in ethanol, followed by the reaction with N‐bromosuccinimide to produce ethyl 2‐(bromomethyl)benzoate
本文介绍了一种简单的方法,用于合成新的4-取代-3-硫代-3,4-二氢苯并[ e ] [1,3]噻嗪酮-5(1 H)-one衍生物。合成基于2-甲基苯甲酸,胺和二硫化碳的两步反应。第一步,使2-甲基苯甲酸与乙醇中的硫酸反应,然后与N-溴琥珀酰亚胺反应生成2-(溴甲基)苯甲酸乙酯。胺和二硫化碳在单独的烧瓶中在碱性介质中反应,生成氨基甲酸二氨基甲酸盐。氨基甲酸硫代氨基甲酸酯和2-(溴甲基)苯甲酸乙酯在二甲基甲酰胺中反应生成所需的4-取代-3-硫代-3-3,4-二氢苯并[ e ] [1,3]噻唑啉-5(1 H)-一阶导数 该方法简单,快速,适用于多种底物,并以高分离产率提供所需产物。

Compounds of the type π-C5H5NiPBu3SC(S)X (X = R, OR and NRH) are obtained from reactions between [π-C5H5Ni(PBu3)2]+Cl− and SC(S)X− in aqueous solution. Compounds such as π-C5H5NiPBu3SC(S)NRH are also obtained by reactions of π-C5H5NiPBu3SH with RNCS.
Design, Synthesis, Molecular Docking, and Cholinesterase Inhibitory Potential of Phthalimide‐Dithiocarbamate Hybrids as New Agents for Treatment of Alzheimer's Disease
of phthalimide-dithiocarbamate hybrids was synthesized and evaluated for in vitro inhibitorypotentials against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). The anti-cholinesterase results indicated that among the synthesized compounds, the compounds 7g and 7h showed the most potent anti-AChE and anti-BuChE activities, respectively. Moleculardocking and dynamic studies of the compounds
A new and easy synthesis of 4‐aryl‐2‐imino‐1,3‐dithiolanes was performed in water/dichloromethane starting from simple precursors, i. e., dithiocarbamate and sulfonium bromide salts. Various possible mechanism pathways were investigated by DFT calculations.
