(Figure Presented) The catalytic asymmetric conjugate addition of a-cyanoketone pronucleophiles to vinyl ketones promoted by a Y/1 catalyst is described. High enantioselectivity was observed for a range of aromatic vinyl ketones, providing 1,5-dicarbonyl compounds bearing an all-carbon quaternary stereogenic center. The product was successfully converted to a spiro-piperidine entity and a bicyclo[3.3.0]octane framework through either the reduction of nitrile or intramolecular pinacol coupling.
