  Lipase catalysed kinetic resolutions of 3-aryl alkanoic acids

  摘要：

  Hydrolase catalysed kinetic resolutions leading to a series of 3-aryl alkanoic acids (>= 94% ee) are described. Hydrolysis of the ethyl esters with a series of hydrolases was undertaken to identify biocatalysts that yield the corresponding acids with excellent enantiopurity in each case. Steric and electronic effects on the efficiency and enantioselectivity of the biocatalytic transformation were also explored. (C) 2011 Elsevier Ltd. All rights reserved.

The scope of alkenes herein include α,β-unsaturated esters, nitriles, and ketones as well as allylic alcohols. Asymmetric deuteration of α,β-unsaturated esters is also achieved with deuterated water, the cheapest deuterium source.

  α-ketoglutarate-dependent aryloxyalkanoate dioxygenases (AADs) are repurposed for applications in biocatalytic oxyfunctionalization. Activity profiling of natural AADs enabled the synthesis of four types of α-and β-hydroxy acids with broad scope, high efficiency, and good selectivity.
