This work describes a synthetic approach to the carbocyclic skeleton of isospongian diterpenes that uses the commercially available monoterpene (S)-carvone as a C-ring synthon, which is incorporated(More)
Diketo-1,3-dioxin-2-ones underwent retro-Diels-Alder reaction on heating in toluene at 110 degrees C to generate alpha,gamma,-triketo-ketenes. These were trapped with alcohols to provide(More)
The diterpenes previously isolated from the leaves of Croton zambesicus were tested to evaluate their vasorelaxant activity on the Wistar rat aorta. Their vasorelaxant effect was compared to a series(More)
The onset temperature of the retro-Diels-Alder reactions of diketo-1,3-dioxin-2-ones to generate alpha,gamma,epsilon-triketo-ketenes was found to be significantly reduced with 2-phenyl substitution.(More)
