found to be a versatile biocatalyst for the desymmetrization of prochiral 3‐arylpentane‐1,5‐diols, based on a two‐step one‐pot oxidation. This procedure has allowed the formation of valuable (S)‐lactones in good to excellent conversions and enantiomeric excess. The catalytic performance of HLADH has been studied using several cofactor regeneration systems and cosolvents, finding great improvements in
已发现马肝醇脱氢酶(HLADH)是基于两步一锅法氧化的前手性3-芳基戊烷-1,5-二醇脱对称的一种多功能生物催化剂。此程序已形成有价值的(S)-内酯,转化率良好,对映异构体过量。已使用多种辅助因子再生系统和助溶剂研究了HLADH的催化性能,发现L-乳酸脱氢酶在活性方面有很大的改善,而使用四氢呋喃时该方法的立体选择性得到了显着改善。对接研究已经揭示了图案替代在该氧化过程的选择性和活性中的重要性。
