摘要
Lucidene and alboatrin are complex benzopyran derived natural products. A key step in their biogenesis may involve a hetero Diels-Alder cycloaddition between an o-quinone methide 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-quinone methide generation.
