prepared in 96% ee by Pseudomonas fluorescens catalysedesterhydrolysis, while, Candida antarcticalipaseB (immob) resolved the α-ethyl substituted 3-arylalkanoic acid (R)-1b in 82% ee. The influence of the position of the substituent relative to the ester site on the efficiency and enantioselectivity of the biotransformation is also explored; the same lipases were found to resolve both the α- and β-substituted
