important and prevalent scaffold in the development of novel leads in medicinal chemistry for a variety of therapeutic targets. A two-step, onepot synthesis of 2,5-disubstituted-1,3,4-thiadiazole derivatives from aryl hydrazides and aryl aldehydes using Lawesson’s reagent is described, yielding 2,5-disubstituted-1,3,4-thiadiazoles in moderate-to-high yields. Based on preliminary biological experiments
五元杂环系统,如噻二唑,仍然是开发各种治疗靶点的药物化学新线索的重要和普遍的支架。描述了使用 Lawesson 试剂从芳基酰肼和芳基醛两步一锅合成 2,5-二取代-1,3,4-噻二唑衍生物,在温和条件下生成 2,5-二取代-1,3,4-噻二唑- 高收益。根据初步的生物学实验,一些新合成的噻二唑显示出抗氧化活性。
