Catalytic alkylation reactions of weakly acidic carbonyl and related compounds using alkenes as electrophiles

Catalytic alkylation reactions of weakly acidic carbonyl and related pronucleophiles such as amides, esters, and sulfonamides with substituted alkenes have been reported. In the presence of a strong Bronsted base catalyst system, potassium hexamethyldisilazide and 18-crown-6 ether, the desired reactions proceeded in high yields at ambient temperature with a wide substrate scope. These are atomeconomical catalytic alkylation reactions of carbonyl and related compounds.
