Synthesis and chemical reactions of 6-chlorosulfonylbenzoxazolin-2-ones [Elektronische Daten] [M. Karimova, D. Dushamov, R. Kuryazov, N. Mukhamedov] The corresponding 6-chlorosulfonyl derivatives were synthesized from benzoxazolin-2-one and its 3-methyl derivative by treatment with chlorosulfonic acid. By treatment of the compounds obtained with water and other nucleophilic reagents (aliphatic and heterocyclic amines) 2-oxobenzoxazoline-6-sulfonic acids and a series of their amides were obtained, while reduction with SnCl2·2H2O gave 6-mercaptobenzoxazolin-2-ones.
