We report an allenylic substitution of racemic tertiary allenylic alcohols with indoles by a cooperative catalyst consisting of iridium/(P,olefin)-ligand catalyst and Lewis acid to give allenylated indoles bearing a quaternary carbon center with good enantioselectivities. 7-Azaindoles also reacted with allenylic alcohols to form the corresponding allenylated products with high enantioselectivities.

铱催化的叔外消旋烯醇与吲哚的不对称烯基取代


我们报道了由铱/（P，烯烃）-配体催化剂和路易斯酸组成的协同催化剂用吲哚取代外消旋叔烯醛的烯基化吲哚，得到带有季碳中心的烯基化吲哚，具有良好的对映选择性。7-氮杂吲哚还与烯丙醇反应，形成相应的具有高对映选择性的烯基化产物。
