α-Acetyl- and α-Cyanovinyl 2,4-Dinitrophenyl Carboxylate as Useful Ketene Equivalents for the Diels-Alder Reaction
MaGee, David I.,Lee, May Ling

Two ketene equivalents (5 and 35) have been developed for use in the Diels-Alder reaction. These dienophiles exhibit a marked increase in reactivity in comparison with the more conventional acetoxyacrylonitrile. Conversions of the cycloadducts to the requisite ketones occurs under mild, and moderate to high yielding conditions.
REGIOSELECTIVITY OF DIELS-ALDER ADDITIONS OF 1-ACETYLVINYL ARENECARBOXYLATES
Aguilar, Raul,Reyes, Alicia,Tamariz, Joaquin

The Diels-Alder addition of "captodative" dienophiles 1-acetylvinyl arenecarboxylates 1b,1d and 1e to 1- and 2-substituted dienes was found highly regioselective.The rate and regioselectivity of this reaction were improved by Lewis acid catalysis.
