A practical and efficient route toward synthesis of amino acid derivatives containing 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 amino acid derivatives at the P3 position resulted in potent HCV NS3 serine protease inhibitors.
利用非对映选择性Strecker反应,已经开发出一种实用而有效的合成含β-季中心氨基酸衍生物的途径。该方法用于制备> 100 g的β-甲基环己基甘氨酸衍生物21。在P3位置掺入一些受阻氨基酸衍生物会产生有效的HCV NS3丝氨酸蛋白酶抑制剂。
