Abstract

Diels-Alder cycloadditions of dienes to some 5-ylidene-2(5H)-furanones have been examined from experimental and theoretical points of view. The role that different substituents play on directing the observed site-selectivity (endocyclic or exocyclic double bond at the dienophile counterpart) is discussed. Several new potential synthetic building blocks have been prepared in good yields. © 1991.
