The ability of horseliveralcoholdehydrogenase (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
