An enantioselective allenylation of aldehydes catalyzed by a chiral, nonracemic phosphoric acid was reported. Under the developed conditions, 1,1′‐disubstituted allenic alcohols were obtained in 64–98% yields with 88–99% ee. Computational studies were conducted to probe the origin of asymmetric induction. Mechanistic studies suggest that the pinacol moiety of the propargylboronate is critical to the
报道了由手性,非外消旋磷酸催化的醛的对映选择性烯丙基化。在发达的条件下,以64-98%的收率和88-99%的ee获得了1,1'-二取代的烯丙醇。进行了计算研究以探究不对称诱导的起源。机理研究表明,炔丙基硼酸酯的频哪醇部分对于由实验数据支持的反应的对映选择性至关重要。
