production of diasteromerically enriched α-aryl carbonyl compounds has been achieved. Although only modest diastereoselectivies are observed, they demonstrate the potential of the method for further optimisation. It also appears that reactions that proceed through a five-membered spirocyclic transition state rearrange, whereas those proceeding through a six-membered transition state do not, but stop at
已经实现了一种新的温和的生产非对映体富集的 α-芳基羰基化合物的方法。尽管仅观察到适度的非对映选择性,但它们证明了该方法进一步优化的潜力。似乎还通过五元螺环过渡态进行的反应重排,而通过六元过渡态进行的反应不会重排,而是在二芳基醚阶段停止。
