Abstract In this study, new bisthiazoles were efficiently synthesized from the reaction of hydrazine-1,2-bis(carbothioamide) with N-aryl-2-oxopropanehydrazonoyl chlorides or N-aryl C-ethoxycarbonyl methanehydrazonoyl chlorides. The formation of the final compounds starts by nucleophilic attack of thiolates to give S-alkylated intermediate, which in situ undergoes nucleophilic addition and intramolecular
摘要 在本研究中,通过肼-1,2-双(碳硫代酰胺)与N-芳基-2-氧代丙烷肼酰氯或N-芳基C-乙氧基羰基甲烷肼酰氯反应高效合成了新型双噻唑。最终化合物的形成开始于硫醇盐的亲核攻击以产生 S-烷基化中间体,其原位经历亲核加成和分子内环化以产生如合成方案中所述的最终产物。从制备的角度来看,廉价且简单的反应条件、试剂的商业可用性、良好的产率和优异的产品纯度使该方法具有重要价值。此外,还评估了新化合物对革兰氏阳性和革兰氏阴性微生物的抗菌活性值。最终产品通过元素分析、傅里叶变换红外光谱 (FT-IR)、质谱 (MS) 和核磁共振 (NMR) 进行鉴定和表征。图形概要
