Synthesis of 9-aryl-9,10-dihydrophenanthrenes by domino [3+3] annulation/ring-opening/Friedel-Crafts alkylation reactions of 1,3-bis(trimethylsilyloxy)-1,3-butadienes with 3-aroyl-5-aryl-4,5-dihydrofurans

The reaction of 1,3-bis(trimethylsilyloxy)-1,3-butadienes with 3-benzoyl-5-aryl-4,5-dihydrofurans, available by CANmediated reaction of styrenes with benzoylacetones, af-forded functionalized 9,10- dihydrophenanthrenes. These reactions proceed by a novel domino [3+3] cyclization/ringopening/ Friedel-Crafts alkylation process.
