Abstract

The enzymatic oxidation of amino alcohols was studied to address the long-standing problem of product stability. Amino aldehydes, highly sought and unstable compounds, can be generated under mild conditions if they are immediately protected. Utilizing a range of alcohol dehydrogenases (ADHs) and semicarbazide as a scavenger, the enantioselective synthesis of protected amino aldehydes is possible. Glycerol dehydrogenase from Gluconobacter oxydans (GoGDH) displayed excellent enantioselectivity but limited substrate scope, whereas horse liver ADH catalyzed a broad range of conversions with low enantioselectivities.
