摘要
A practical and efficient route toward synthesis of amino acid derivatives containing P-quaternary center has been developed using diastereo selective Strecker reaction. The method was employed for preparation of > 100 g of P-methylcyclohexyl glycine derivative, 21. Incorporation of some of the hindered amino acid derivatives at the P3 position resulted in potent HCV NS3 serine protease inhibitors. (c) 2007 Elsevier Ltd. All rights reserved.
