involve a hetero Diels-Alder cycloaddition between an o-quinonemethide intermediate with a simple, or activated tri-substituted olefin. Experimental evidence is provided to support this hypothesis, with the biomimetic synthesis of both (+/-)-lucidene and (+/-)-alboatrin successfully achieved using a new and efficient method for o-quinonemethidegeneration.
