α-Acetyl- and α-Cyanovinyl 2,4-Dinitrophenyl Carboxylate as Useful Ketene Equivalents for the Diels-Alder Reaction

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.

Highly efficient synthesis of the natural spiro-terpenoid (±)-andirolactone

A synthesis of the natural terpenoid sporilactone (±)-andirolactone (1) is described. Condensation of dimethyl malonate (9) with 1-acetyl-4-methyl-3-cyclohexen-1-ol (3), prepared by Diels-Alder reaction of olefin 5 and isoprene (4), and thermal decarboxyl

REGIOSELECTIVITY OF DIELS-ALDER ADDITIONS OF 1-ACETYLVINYL ARENECARBOXYLATES

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.
