Burkholderia cepacia lipase is an excellent enzyme for the enantioselective hydrolysis of β-heteroaryl-β-amino esters
摘要:
The enantioselective (E > 200) lipase PS-catalysed hydrolysis of beta-heteroaryl-beta-amino esters is described. The reactions were performed with H2O (0.5 equiv) in either diisopropyl ether or tert-butyl methyl ether at 25 degrees C. The resulting beta-heteroaryl-substituted beta-amino acid enantiomers were formed in high enantiomeric excess (ee >= 97%) and in good yield (>= 40%). (c) 2009 Elsevier Ltd. All rights reserved.

The development of a commercial manufacturing route for (S)-beta-phenylalanine 8, a key pharmaceutical building block, is described. The different approaches which were investigated, based on catalytic asymmetric hydrogenation of enamide intermediates and on biocatalysis using acylase and lipase hydrolyses, are compared. The lipase resolution route was chosen for scale-up, and the final two-step process, based on readily available raw materials, is shown to be robust at full manufacturing scale
