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.

Venturello's peroxophosphotungstate compound and Ti(O(i)Pr)(4) were successfully used as catalysts for the epoxidation-alcoholysis of various dihydropyrans and dihydrofuran using H(2)O(2) as the oxidant. Different alcohols can be used as solvents and nucleophiles, resulting in hydroxy ether products with varying alkoxy
