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.

Absolute stereochemistry of oils and viscous liquids can be difficult to determine. Co-crystallization involves generating a crystalline material consisting of more than one neutral compound. The combination of co-crystallization with both X-ray diffraction and chiral HPLC was particularly powerful in overcoming these difficulties for a series of chiral 3-arylbutanoic acids. Co-crystallization offers
