A stereoselective methodology was developed to construct synthetically and pharmaceutically useful chiral chromene derivatives. In the presence of a newly designed bifunctional tertiary amine-squaramide organocatalyst, the Michael addition between cyclic 1,3-diketones and β,γ-unsaturated α-ketoesters occurred smoothly to provide the desired products with high to excellent yields (84%~97%) and enantioselectivies (79%~97% ee). This catalytic protocol was compatible with a range of structurally distinct β,γ-unsaturated α-ketoesters.

Key words: Michael addition, organocatalysis, tertiary amine-squaramide, cyclic diketone, β,γ-unsaturated α-ketoesters
