reactions of acyclic and cyclic allylic alcohols for the stereoselective introduction of ethyl, 2-silylethyl, 2-phenethyl, and alkenyl groups. Cross-coupling of an allylic alcohol with a vinylsilane or styrene derivative is particularly noteworthy, as an efficient cross-selective coupling of two alkenes has been elusive. The stereochemistry of the cross-coupling alkylation is consistent with syn addit
我们开发了低价钛介导的无环和环状烯丙醇的 1,3-转正交叉偶联反应,用于立体选择性引入乙基、2-甲硅烷基乙基、2-苯乙基和烯基。烯丙醇与乙烯基硅烷或苯乙烯衍生物的交叉偶联特别值得注意,因为两种烯烃的有效交叉选择性偶联一直难以捉摸。交叉偶联烷基化的立体化学与顺式加成/β-消除一致。
