Synthesis of biaryls, fluorenones, cyclopenta[def]phenanthren-4-ones, and benzophenones based on formal [3+3] cyclocondensations of 1,3-bis(silyloxy)buta- 1,3-dienes with 3-(silyloxy)-2-en-1-ones

Functionalized fluorenones were efficiently prepared in four steps. The [3+3] cyclization of 1,3-bis(silyloxy)buta-1,3- dienes with 3-(silyloxy)-2-en-1- ones afforded salicylates that were transformed into their enol triflates. The Suzuki cross-coupling r
