Synthesis of New Thiazolidinones and Thiazoles in Indole Series

Abstract

Recent findings confirm that thiosemicarbazones and thiazoles offer a wide range of biological properties. We report here the synthesis of two series of highly functionalized thiazole-derived compounds from the reactions of various indole-derived thiosemicarbazones with diethyl acetylenedicarboxylate and 4-bromophenacyl bromide. As a result, a series of new derivatives of thiosemicarbazone, thiazolidinone, and thiazole bearing an indole moiety was synthesized and developed in good yields.
