A practical and efficient route toward synthesis of aminoacidderivativescontaining β-quaternary center has been developed using diastereoselective Strecker reaction. The method was employed for preparation of >100 g of β-methylcyclohexyl glycine derivative, 21. Incorporation of some of the hindered aminoacidderivatives at the P3 position resulted in potent HCV NS3 serine protease inhibitors.
