Cyclization Reactions of β,γ‐Unsaturated Derivatives of Carbonic Acid. V. Reactions of β,γ‐Unsaturated Carbamic Acid Esters with Sulfenyl Chlorides — Synthesis of 3,5,5‐Trisubstituted Oxazolidine‐2‐ones N,N‐Disubstituted β,γ‐Unsaturated urethanes 1 have been cyclized to 3,5,5‐trisubstituted oxazolidine‐2‐ones 3 by aromatic sulfenyl chlorides in methylene chloride. The same oxazolidine‐2‐ones 3 were obtained by reaction of 5‐bromomethyloxazolidine‐2‐ones 8 with thiophenols.
