  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.

  Candida antarctica lipase A—a powerful catalyst for the resolution of heteroaromatic β-amino esters

  摘要：

  Enantioselective acylations of 3-amino-3-beteroarylpropanoates (ArCH(NH2)CH2CO2Et; Ar = 2- or 3-thienyl or -furyl) were performed in the presence of Candida antarctica lipase A. As a result of the excellent chemo- and enantioselectivities (E > 100), gram-scale resolutions were carried out in ethyl butanoate. The hydrochloride salts of the unreacted R substrates and the butanamides of the reactive S enantiomers were thus prepared. (C) 2002 Elsevier Science Ltd. All rights reserved.
