Synthesis of novel orthogonally protected 1,3,4-thiadiazole and 1,3,4-oxadiazole tethered dipeptide mimetics is described. Both the heterocycles are prepared via a set of diacylhydrazines derived from amino acids. 1,3,4-Thiadiazoles are synthesized by dehydrosulfurization using Lawesson’s reagent while 1,3,4-oxadiazoles are obtained by EDC mediated cyclodehydration.
描述了新型的正交保护的1,3,4-噻二唑和1,3,4-恶二唑连接的二肽模拟物的合成。这两个杂环是通过一组衍生自氨基酸的二酰基肼制备的。1,3,4-噻二唑是通过使用Lawesson试剂进行脱硫而合成的,而1,3,4-恶二唑是通过EDC介导的环脱水获得的。
