Thiazolium azomethine ylides, generated from 1,3-thiazoles equipped with a C-2 methanethiol group, participated in an efficient [3+2] cycloaddition reaction with acetylene derivatives to yield unique pyrrolo[2,1-b]thiazoles. The elimination of the methanethiol leaving group from the cycloadduct replaced the need for a sep. oxidation step and suppressed ring-opening side reactions. Products were obtained in short synthetic sequences to demonstrate their use as a scaffold for compound libraries.
