1. Introduction
Over the last few years, processes have been developed, using hydrolases, oxidoreductases or lyases as biocatalysts in pharmaceutical, agricultural, or synthetic organic chemistry industry. Lipases (triacylglycerol acyl hydrolases) exhibit wide substrate specificity, stereoselectivity and enantioselectivity and are therefore, industrially significant enzymes [1,2]. The use of lipases in non-aqueous environments proves an excellent methodology for the preparation of single-isomer chiral drugs by enzymatic hydrolysis,transesterificationoraminolysisreactions.Applications of lipases in asymmetric synthesis include kinetic resolution of racemic alcohols, acids, esters or amines, as well as the desymmetrization of prochiral compounds [3–7]. In the pharmaceutical industry, there has been an ever-increasing trend for chiral drug substances to focus enantiomers instead of racemic mixtures,
