Abstract A series of racemic 4-aryl-5-(tert-butoxycarbonyl)-6-methyl-3, 4-dihydro-2 (1H)- pyridones have been prepared by means of a modified Hantzsch reaction using commercially available starting materials. An easy removal of the tert-butyl group of these pyridones and subsequent reaction with cesium carbonate and chloromethyl 2- methylpropanoate provided us suitable substrates (±)-5 to be used in lipase-catalyzed ...
