Abstract

(formula presented) The Diels-Alder reaction of activated dihydropyrones with electron-rich dienes proceeds with synthetically useful levels of diastereoselectivity. Product ratios vary with the nature and location of substituents on diene and dienophile, as well as with reaction conditions. Lewis acid catalyzed reactions of related pyrone and benzopyrone dienophiles are also diastereoselective.
