A novel α,β-regioselective [3+2] cycloaddition reaction of arylallene with C,N-cyclic azomethine imine is reported. The axial-to-central chirality transfer phenomenon has been disclosed with chiral allenes in the reaction. The wide substrate scope, including different functional groups and natural products, reveals the generality of the methodology. Both experiments and density functional theory calculations
报道了芳基丙二烯与 C,N-环偶氮甲亚胺的新型 α,β-区域选择性 [3+2] 环加成反应。反应中的手性丙二烯已经揭示了轴向到中心的手性转移现象。广泛的底物范围,包括不同的功能组和天然产物,揭示了该方法的普遍性。实验和密度泛函理论计算都已被用来阐明一个似是而非的机制。
