Conjugated addition of lithium dimethylcuprate to α,β-unsaturated ketones gives intermediate enolates which, treated with acetyl chloride, undergo O- and/or C-acylation depending on the substitution at the enone β-carbon.Results agree with the hypothesis that C-acylation proceeds through an intramolecular metal-assisted mechanism.
Regio- and Stereoselective 1,2 Wagner-Meerwein Shifts during Trifluoroacetic Acid Catalyzed Isomerization of Unsymmetrically Substituted Tricyclo2,4>heptanes
