most of the chemically synthesized compounds are produced as racemates their kineticresolution has been of great interest. For this purpose a number of chemo-enzymatic approaches were proposed. One of such approaches, the use of isolated lipases, is a well-established alternative. Herein we report the kineticresolutions of 2-Substituted five-membered heteroaromatic rings. By optimizing the reaction

Nonactin, produced by Streptomyces griseus ETH A7796, is a macrotetrolide assembled from nonactic acid. It is an effective inhibitor of drug efflux in multidrug resistant erythroleukemia K562 cells at sub-toxic concentrations and has been shown to possess both antibacterial and antitumor activity. As totalsynthesis is impractical for the generation of nonactin analogs we have studied precursor-directed
