Enzyme-catalysed hydrolysis of N-benzyloxycarbonyl-cis-2,6-(acetoxymethyl)piperidine. A facile route to optically active piperidines
摘要:
We report the first enzymatic asymmetrization of a piperidine system. Hydrolysis of N-benzyloxycarbonyl-cis-2,6-(acetoxymethyl)piperidine in the presence of Aspergillus niger lipase gave the corresponding 2R, 6S mono-acetate in good chemical yield and very high optical purity (ee greater-than-or-equal-to 98%).
