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
