Palladium‐Catalyzed CH Activation of Methoxy Groups: A Facile Synthesis of Substituted 6<i>H</i>‐Dibenzo[<i>b</i>,<i>d</i>]pyrans

Abstract

A threefold domino coupling reaction of ortho-iodoanisole (1) affords dibenzopyran 2 in high yield (90%). This C-H activation at a methoxy group is a new reaction principle in palladium-catalyzed reactions.
