A cinchona alkaloid-catalyzed domino Michael/hemiacetalization reaction of cyclic beta-oxo aldehydes and aromatic beta,gamma-unsaturated alpha-keto esters, resulting in the formation of spiro-dihydropyran architectures in good yield with high stereoselectivity (up to 97% ee), is presented.

A simple chiral diamine catalyst (1a) was successfully applied in the asymmetric Michael reaction between cyclic dimedone and α,β-unsaturated ketones. Both acyclic enones with aryl or alkyl β-substituents and cyclic enones were tolerated well in the reaction. The desired adducts
