Although the reaction of heterosubstituted allylic carbanions (2) with aldehydes generally produces a mixture of the γ- and α-adducts (4 and 3), syn-3 and anti-3 can be prepared either exclusively or predominantly by the proper choice of the organometallic compound added.
虽然杂取代碳负离子烯丙基(反应2)与醛通常产生γ-和α-加合物的混合物(4和3),顺式- 3和抗- 3既可以完全或主要由的适当选择制备添加有机金属化合物。
