The ability of horse liver alcohol dehydrogenase (HLADH) to the enantioselective oxidation of primary–primary, primary–secondary and primary-tertiary aliphatic 1,5- and 1,6-diols 1a–i was studied. No enantioselectivity of the transformations of primary–primary 1,6-diols 1a–d to ɛ-lactones 4a–d was observed. Regioselective oxidation of primary–secondary 1,6-diols 1e,f and 1,5-diols 1h,i afforded enantiomerically
研究了马肝醇脱氢酶(HLADH)对伯,伯,伯,仲和伯叔脂肪族1,5-和1,6-二醇1a – i的对映选择性氧化的能力。没有观察到伯-伯1,6-二醇1a - d转化为β-内酯4a - d的对映选择性。主要-辅助-1,6-二醇的区域选择性氧化1E,˚F和1,5-二醇1h中,我得到对映体富集ɛ内酯4E,˚F和δ内酯4H,我。L-内酯4e,f形成较高的对映体过量(ee = 85–99%)。1g伯叔叔二醇的酶促氧化反应未得到内酯产物。
