| Abstract | |
The Biginelli synthesis is a classic tricomponent reaction known to result in polyfunctionalized dihydropyrimidinone (DHPM) derivatives. Herein, we described a chemo-enzymatic strategy for obtaining enantiomerically enriched hydroxy-DHPMs. These compounds were previously esterified with butyric or acetic anhydride and were later submitted to hydrolysis reactions catalysed by lipase B from Candida antarctica. Although the stereogenic centre is far from the reaction site (4-5 bonds), moderate to excellent enantiomeric excess values were obtained (up to 99%). Docking studies were performed in parallel to elucidate the binding modes of some molecules with the CALB active site, and were able to provide information on the enantiospecificity of these compounds in the hydrolysis reaction.
