We herein report a Ni-catalyzed three-component cross-electrophile coupling of 1,3-dienes with aldehydes and aryl bromides using manganese metal as the reducing agent. This efficient protocol accomplishes dicarbofunctionalization of 1,3-dienes to synthesize diverse structural 1,4-disubstituted homoallylic alcohols by forming two new C–C bonds in one time. Mechanistic study suggests that an allyl-nickel(I)
我们在此报道了使用锰金属作为还原剂的 1,3-二烯与醛和芳基溴化物的 Ni 催化的三组分交叉亲电偶联。这种有效的方案通过一次形成两个新的 C-C 键来完成 1,3-二烯的二碳官能化,从而合成不同结构的 1,4-二取代高烯丙醇。机理研究表明,烯丙基镍 (I) 物种参与了催化循环。
