Phenyl (trichloromethyl) carbinol reacts with bifunctional reagents containing nucleophilic sulfur such as thioureas, thiobenzhydrazide, o-aminothiophenol, etc., in a series of steps involving an initial attack of the sulfur anion on the intermediate epoxide 2 followed by ring closure to a heterocyclic compound. Thiazolidinones, thiadiazinones, benzothiazinones, and thiomorpholinones are easily obtained in yields ranging from 57-20%. ...
