were obtained from 3-(hydroxymethyl)lactams 2 and 2a by a direct dehydration with dicyclohexylcarbodiimide using cuprous iodide as a catalyst. Introduction of the sulfhydryl group was accomplished by a Michael addition of these alpha, beta-unsaturated lactams. The compound with the highest in vitro activity was 3-(mercaptomethyl)-2-oxo-1-piperidineacetic acid (7a). The activity of the 7a both in vitro
