Preparation of 4‐substituted 1,3‐oxathiolan‐5‐ones via the sulphenium ion intermediate generated by the pummerer rearrangement

Abstract: 4‐Substituted 1,3‐oxathiolan‐5‐ones have been synthesized via the Pummerer rearrangement from the S‐oxide of the parent molecule. The 4,5‐dione is obtained in the presence of pyridine N‐oxide.
