摘要: A new and mild method for the production of diasteromerically enriched α-aryl carbonyl compounds has been achieved. Although only modest diastereoselectivies are observed, they demonstrate potential further optimisation. It also appears that reactions proceed through a five-membered spirocyclic transition state rearrange, whereas those proceeding six-membered do not, but stop at diaryl ether stage.
