Diisopropylsilyl bis-enol ethers are shown to be powerful intermediates for the diastereoselective dimerization and cross-coupling of cyclic ketones. The trends observed for the oxidative coupling of a range of different dialkylsilyl bis-enol ethers derived from cyclohexanone are rationalized by invoking a stereochemical model based on a Thorpe−Ingold effect.
