  Asymmetric reductive amination of boron-containing aryl-ketones using ω-transaminases

  摘要：

  The asymmetric reductive amination of aryl-ketones bearing various boron-functionalities (acid, ester or potassium trifluoroborates) was investigated employing enantiocomplementary omega-transaminases as catalysts. Under the optimized conditions, high conversions (up to 94%) and excellent ee's (up to >99%) were obtained providing access to both (R)- and (S)-configured amino-aryl boronates under mild reaction conditions.

• Chemoenzymatic synthesis of boron-containing chiral amines and amides

  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.
