  Chemoenzymatic preparation of optically active 4-aryl-5-carboxy-6-methyl-3,4-dihydro-2(1H)-pyridone derivatives

  摘要：

  A series of racemic 4-ary1-5-(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 hydrolysis reactions. Lipase B from Candida antarctica (CAL-B) was the most adequate lipase in the hydrolysis of (+/-)-5. Despite the low enantioselectivity values obtained (E <= 12), several optically active pyridone derivatives were finally isolated with high enantiomeric excesses (ee >= 91%) and moderate yields.
