An ambident electrophilicity of phosphinicacid thioesters is disclosed. Unexpected carbon-sulfur bond formation took place in the reaction between phosphinicacid thioesters and benzyl Grignard reagents. The developed method for benzyl sulfides has a wide substrate scope and was applicable for the synthesis of a drug analog.

Synthetic approaches to novelenantiomericallypure sulfides and selenides derived from (+)-camphor and (+)-camphor-10-sulfonate esters are described. Lewis acid mediated hemiacetal formation between a camphor-derived ketone and a thiol or selenol, and subsequent in situ reduction using triethylsilane selectively gives the exo-sulfide or -selenide in moderate overall yields. The initial sulfonate ester
