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.
