Diels-Alder cycloadditions of the cyclopropenone ketal 1 with representative electron-deficient, electron-rich and neutral dienes are presented.The results observed are consistent with the potential for the strained olefin of the cyclopropenone ketal to exhibit accelerated participation in both inverse electron demand (LUMOdiene controlled) and normal (HOMOdiene controlled) Diels-Alder reactions.Approaches to the introduction of cycloheptatrienones, tropones, based on the room temperature and pressure-promoted Diels-Alder reactions of the cyclopropenone ketal 1 are presented.
