I2-Promoted [3+2] Cyclization of 1,3-Diketones with Potassium Thiocyanate: a Route to Thiazol-2(3H)-One Derivatives

An I2-promoted strategy has been developed for the synthesis of thiazol-2(3H)-one derivatives from 1,3-diketones with potassium thiocyanate. This [3+2] cyclization reaction involves C?S and C?N bond formation and exhibits good functional group tolerance. A series of thiazol-2(3H)-one derivatives are obtained in moderate to good yields. (Figure presented.).

A convenient synthesis of 5/7-chloro-4H-1, 4-benzothiazines

5/7-Chloro-4H-1,4-benzothiazines have been synthesized by the condensation of sustituted 2-amino-3/5-chlorobenzenethiol with compounds containing active methylene group in dimethylsulfoxide which causes oxidative cyclization via enaminoketone intermediate. The IR, NMR and Mass spectra have been also included.
