Diastereoselective enolate alkylation reactions of N-acylsulfinamides and conversion of the alkylation products to a variety of enantiopure products are reported. Several sulfinamides were prepared in solution followed by acylation to provide N-acylsulfinamides. The N-acylsulfinamides were then evaluated in diastereoselective enolate alkylation reactions. Of the sulfinamides evaluated, tert-butanesulfinamide
