Stereochemistry of Enantioselective Deprotonation of 4-Substituted

Cyclohexanones by Chiral Bidentate Lithium Amides.

-Enantioselective deprotonation of 4-substituted cyclohexanones using chiral lithium amide bases such as (I) in the presence of excess trimethylsilyl chloride results in formation of the corresponding silyl enol ethers with good e.e. The bulky amide (II) gives a significant lower stereoselectivity. -(TORIYAMA, M.;
