✦ Synopsis

A practical method for the synthesis of b-hydroxymercaptans has been successfully developed through the ring-opening of epoxides with organic dithiophosphorus acids 1. Highly regio-and stereoselective products, b-hydroxyalkyl dithiophosphates, which were transformed to the corresponding synthetically valuable b-hydroxymercaptans by further reduction, were obtained under mild reaction conditions without any catalyst or promoter. Highly enantioselective ring-opening reaction of cyclohexene epoxide with 1 was realized in the presence of a chiral (salen)Ti(IV) complex.
