A new access to alkyl-α-ketoglutaric acids, precursors of glutamic acid analogues by enzymatic transamination. Application to the synthesis of (2S,4R)-4-propyl-glutamic acid
摘要:
4-Alkyl-2-alkylidene-glutaric acids are easily obtained by a Claisen-Johnson rearrangement, providing a short access to 4-alkyl-alpha-ketoglutaric acids. These compounds are substrates of the glutamic oxalacetic transaminase (GOT), allowing the enzymatic synthesis of biologically important analogues of L-glutamate. A new analogue, (2S,4R)-4-propyl-glutamic acid, is described. (C) 1999 Elsevier Science Ltd. All rights reserved.
