Abstract
The tricarbonyl complex prepared from 1-trifluoromethyldihydronaphthal ene and Cr(CO)3(NH3)3 undergoes Diels-Alder cycloaddition under high-p ressure conditions (15 kbar) to give after decomplexation by natural l ight and deprotection, the tetrahydrophenanthrone product in 65% yield . This new methodology allows the activation of unreactive styrenes in Diels-Alder cycloaddition.
