In an ongoing project we required a wide variety of α-bromo/iodo ketones for our work on the synthesis of carbocyclic natural products involving a tandem cyclization of a α-carbonyl radical. The required silyl-enol ethers were smoothly prepared via a CuI promoted 1,4-addition of various Grignards to enones. Initially the iodination/bromination of silyl-enol ether 1a was tried using NIS/NBS without any success. The existing procedure for iodination using NaI/m- ...
