  Chemoenzymatic synthesis of boron-containing chiral amines and amides

  摘要：

  The first application of lipases as catalysts to obtain optically active boron-containing amines and amides is described. We studied several reaction conditions to achieve the kinetic resolution of boron-containing amines via enantioselective acylation mediated by Candida antarctica lipase B (CAL-B). Excellent enantioselectivity (E>200) and high enantiomeric excess (up to >99%) of both the remaining amines and amides were obtained. (C) 2010 Elsevier Ltd. All rights reserved.
