    摘要: This invention relates to a process for preparing dicarboxylic acid monoesters from cyanocarboxylic acid esters. More particularly, using the nitrilase from Acidovorax facilis 72W (ATCC 55745) in various forms as an enzyme catalyst, an aliphatic or aromatic cyanocarboxylic acid ester is converted to the corresponding dicarboxylic acid monoester with high chemoselectivity at 100% conversion. An embodiment of the invention also provides a process for obtaining high chemoselectively and high regioselectivity.
