The present invention relates to a novel class of &agr;-aminoboronic acids of Formula (V),
which are useful as intermediates in synthetic processes for inhibitors of the serine proteases, leukocyte elastase, pancreatic elastase, cathepsin G, and chymotrypsin. More specifically, the &agr;-aminoboronic acids are useful as intermediates for the synthesis of Hepatitis C Virus (HCV) protease inhibitors. This invention also generally relates to novel methods for the preparation of &agr;-aminoboronic acids.
本发明涉及一种新型的α-氨基硼酸类化合物,其化学式为(V),这些化合物在合成丝氨酸蛋白酶、白细胞弹性蛋白酶、胰蛋白酶、猫hepsin G和胰蛋白酶抑制剂的合成过程中作为中间体是有用的。更具体地,α-氨基硼酸类化合物在合成丙型肝炎病毒(HCV)蛋白酶抑制剂中是有用的中间体。本发明还普遍涉及一种制备α-氨基硼酸的新方法。
