Treatment of enantiomerically enriched epoxy mesylates 7-9 with potassium alkoxides under carefully controlled reaction conditions (18-crown-6, THF, -78 degrees C) provide the corresponding alpha-alkoxyketones 10-13 without significant racemisation. The reactions are shown to proceed with net stereochemical inversion at the epoxide centre. (C) 1997, Elsevier Science Ltd.
