  Chemoenzymatic Synthesis of Glutamic Acid Analogues:  Substrate Specificity and Synthetic Applications of Branched Chain Aminotransferase from Escherichia coli

  摘要：

  [GRAPHICS]A new route to alpha-keto acids is described, based on the ozonolysis of enol acetates obtained from alpha-substituted beta-keto esters. Escherichia coli branched chain aminotransferase (BCAT) activity toward a variety of substituted 2-oxoglutaric acids was demonstrated analytically. BCAT was shown to have a broad substrate spectrum, complementary to that of aspartate aminotransferase, and to offer access to a variety of glutamic acid analogues. The usefulness of BCAT was demonstrated through the synthesis of several 3- and 4-substituted derivatives.

  The syntheses of optically pure 4,4-dimethyl-L-glutamic acid as well as (2S,4R)- and (2S,4S)-4-hydroxy-4-methylglutamic acids have been achieved by transamination of the corresponding 2-oxo-4,4-dimethyl- and rac-2-oxo-4-hydroxy-4-methylglutaric acids using glutamic oxalacetic transaminase (GOT).
