Cyclization Reactions of β,γ‐Unsaturated Derivatives of Carbonic Acid. VII. Synthesis of Unequivocal N‐Acylated Thiazolidine‐2‐ones and Oxazolidine‐2‐ones
A new synthetic route to N‐acylated thiazolidine‐2‐ones and oxazolidine‐2‐ones is reported: The reaction of carboxylic acid chlorides with 2‐alkoxy‐2‐thiazolines (1, 2) or ‐2‐oxazolines (3) yields unequivocal N‐acylated thiazolidine‐2‐ones (4–6) or oxazolidine‐2‐ones (7). Bifunctional acid chlorides, e.g. oxalyl chloride or thiophosgene yield compounds 11 and 12.
