ALPHA-AMINOBORONIC ACIDS PREPARED BY NOVEL SYNTHETIC METHODS

摘要

The present invention relates to a novel class of alpha -aminobo ronic 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 alpha -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 alpha -aminoboronic acids.
