摘要

我们报告了在铱/（P，烯烃）-配体催化剂和路易斯酸组成的协同催化剂作用下，外消旋叔代异烯醇与吲哚的异烯取代反应，从而以良好的对映选择性得到带有季碳中心的异烯化吲哚。7-Azaindoles 还能与别烯醇反应生成相应的别烯化产物，对映选择性很高。

Iridium-Catalyzed Asymmetric Allenylic Substitution of Tertiary Racemic Allenylic Alcohols with Indoles

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.
