2-Pyridylmethyl ether: a readily removable and efficient directing group for amino acidligand accelerated ortho-C–H olefination of phenols

Abstract

2-Pyridylmethyl ether-directed ortho-C-H olefination of phenols via a seven-membered cyclopalladated intermediate has been disclosed to construct a variety of ortho-alkenyl phenols and ortho-alkyl phenols.
