A Concise Approach to the Synthesis of <i>opp</i>-Dibenzoporphyrins through the Heck Reaction

Abstract

A concise approach to the synthesis of functionalized opp-dibenzoporphyrins is described. In this method, introduction of alkenyl groups to the porphyrin periphery through the vicinal 2-fold Heck reaction, 6-pi electrocyclization, and subsequent aromatization occur in one pot.
