The natural anti selectivity of the Horner-Wittig reaction with phosphine oxides is reduced when there is a branched chain next to the new CC double bond A better approach is Luche reduction of the corresponding ketones which gives high anti selectivity when the branched chain is placed on the side chain next to the phosphine oxide.
当在新的CC双键旁边有支链时,与氧化膦反应的Horner-Wittig反应的自然抗选择性降低。更好的方法是将相应的酮Luche还原成相应的酮,当将支链置于C上时具有较高的抗选择性。氧化膦旁的侧链。
