The syntheses of different enantiomerically N-acyl N-alkyl p-toluenesulfinamides 5, by N- sulfinylation of primary amines with (S)-menthyl-p-tolylsulfinate followed by N-acylation of the resulting sulfinamides are reported. Their reactions with some C-nucleophiles take place at the sulfur atom exclusively with complete retention of the enantiomeric purity, revealing their ability as sulfinylating agents. In this sense, their comparison with other reagents ...
