  Influence of ester chain length, enzyme, and physical parameters on lipase-catalysed hydrolyses of meso-oxiranedimethanol esters. Part 2

  摘要：

  A range of meso-oxiranedimethanol diesters were prepared and subjected to hydrolysis by a selection of microbial and porcine-derived lipases. The best chain length was then subjected to a wider range of lipases. The physical reaction parameters were further investigated for the best enzyme/substrate combination. The results revealed the effects of ester chain length, choice of enzyme, and physical reaction parameters on the enzymic hydrolysis. Using a combination of the these three variables, it is demonstrated that this is a versatile approach for the optimisation of an enzymic hydrolysis for a given substrate. Additionally, we also report on an efficient, multigram synthesis of oxiranedimethanol diesters from cheap achiral precursors, their successful enzymic hydrolyses to alcohols in good chemical yield and e.e., and their conversion to synthetically useful aldehydes in high yield. Both enantiomeric series can readily be accessed from a single enzymic hydrolysis result. (C) 2000 Elsevier Science Ltd. All rights reserved.
