Abstract

-Carbamoylsulfoxides undergo a novel intramolecular Pummerer-type reaction with O-silylated ketene acetal in dry acetonitrile in the presence of a catalytic amount of zinc iodide to give a-thiolactams in good to excellent yields under nearly neutral conditions. © 1990, The Pharmaceutical Society of Japan.
