Synthetic equivalents: 1‐Alkenylboronates perform the role of an allylating reagent. Their reaction with aldehydes in the presence of a cationic rhodium(I)/dppm catalyst results in a highly diastereoselective production of anti‐configured homoallylic alcohols (see scheme; Bpin=4,4,5,5‐tetramethyl‐1,3,2‐dioxaborolanyl).
合成等效物:1-烯基
硼酸酯起烯丙基化试剂的作用。它们在阳离子
铑(I)/ dppm催化剂存在下与醛的反应导致非构型高选择性生成反构型均烯丙基醇(参见方案; Bpin = 4、4、5、5-四甲基-1,3,2 -二氧杂
硼硼烷基)。
