A recently developed homochiral magnesium amide base has been shown to be highly effective in the asymmetric deprotonation of cis-2,6-disubstituted cyclohexanones, affording excellent levels of both conversion and enantioselection (up to > 99.5 : 0.5 e.r.). In addition, a novel kinetic resolution process has been realised with the corresponding trans-disubstituted substrates, allowing access to optically enriched enol ethers and chiral ketones.
