Versatile Route to Substituted Ketones through Charge-Directed Conjugate Addition Reactions

Charge-directed conjugate addition reactions have been applied to the preparation of highly substituted ketones.Acylphosphoranes resulting from conjugate addition-alkylation reactions are reduced by Al-Hg to β-keto esters, which, upon alkylation and hydrolysis, give ketones in high yields.An application of this methodology to the synthesis of 9, the defense substance of L. longipes, is described.
