Catalytic, Asymmetric Michael Reactions of Cyclic Diketones with β,γ-Unsaturated-α-ketoesters

[Image: see text] Newly synthesized cinchona alkaloid-derived pyrimidines function as effective asymmetric catalysts for the Michael reaction between cyclic diketones and β,γ-unsaturated-α-ketoesters. The reactions of electrophiles with either aryl or alkyl γ-substituents give 64−99% yields and 94−9...
