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.
