Domino Oxidative [Pd]-Catalysis: One-Pot Synthesis of Fluorenones Starting from Simple Benzylamines and Iodo Arenes

A domino [Pd]-catalysis for the efficient synthesis of fluorenones is presented. The overall reaction proceeds through the formation of a five membered Pd(II)-cycle via a highly regioselective ortho C(sp2)-H activation(s) of simple benzylamine that combines with external iodo arenes to give ortho arylated products. Significantly, the reaction further activates the C(sp3)-H and C(sp2)-H (intramolecular oxidative Heck coupling) bonds to give tricyclic imine systems. Then the usual water workup affords the fused tricyclic ketones (fluorenones). Remarkably, this one-pot operation enabled the effective construction of two C-C to three C-C bonds

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
