A chemoenzymatic preparation of both enantiomers of ω-hydroxymethyl-substituted lactones
摘要:
(R)- and (S)-delta-hydroxymethyl vaterolactone and epsilon-hydroxymethyl caprolactone were prepared as tert-butyldiphenylsilyl derivatives, in good yields and high enantiomeric purities, in a 5 step sequence, starting from the microbial stereospecific reduction of ethyl 2-oxocyclopentane or 2-oxocyclohexane carboxylates respectively.
