Cyclization Reactions of β,γ‐Unsaturated Derivatives of Carbonic Acid. X. Reaction of N‐Cinnamyl Carbamic Acid Esters with Sulfenyl Chlorides—Synthesis of 3,5‐Disubstituted Oxazolidine‐2‐ones N‐Cinnamyl urethanes 1 have been cyclized to 3,5‐disubstituted oxazolidine‐2‐ones 3 by aromatic sulfenyl chlorides in methylene chloride. The tetrahydro‐2H‐1,3‐oxazine‐2‐ones 6 were obtained by reaction of 5‐bromotetrahydro‐2H‐1,3‐oxazine‐2‐ones 8 with thiophenols.
