Abstract

Abstract An efficient and rapid, solvent-free, microwave-accelerated, one-pot, three- component protocol for the synthesis of spirothiazolidin-4-ones from organic azides is reported for the first time via Staudinger/aza-Wittig coupling/cyclization. The solvent-free approach overcomes the limitations associated with the prevailing solution-phase methodologies in the case of amines. In particular, its novelty is that it eradicates the vital ...
