摘要
Treatment of the diastereomeric O,Se-ketals cis- or trans-4 with lithium naphthalenide provided, through stereoselective reduction of the radical intermediate 5, the axially lithiated cyclohexyl ether trans-6, trans-6 gave the equatorially benzylated cyclohexanol cis-5 stereoselectively after [1,2]-Wittig rearrangement and aqueous work-up.
