✦ Synopsis

Cyclization Reactions of β,γ‐Unsaturated Derivatives of Carbonic Acid. IV. Synthesis of N‐Substituted Thiazolidine‐2‐ones and 2‐Alkoxy‐2‐thiazolines from β,γ‐Unsaturated Thiocarbamic Acid Esters

The reaction between N‐substituted β,γ‐unsaturated thiourethans and dry hydrogen chloride or bromine occurs in methylene chloride at room temperature. The thiourethans 1 a–4 a react with hydrogen chloride to give mixtures of corresponding 2‐alkoxy‐2‐thiazolines 6–9 and the thiazolidine‐2‐one 11 a. A useful synthetic route to N‐substituted thiazolidine‐2‐ones 11 is demonstrated by the reaction of N,N‐disubstituted β,γ‐unsaturated thiourethans with hydrogen chloride and bromine. The i.r. and H‐n.m.r.‐data of the compounds are described.
