Pd-Catalyzed π‑Chelation Assisted <i>ortho</i>-C–H Activation and Annulation of Allylarenes with Internal Alkynes

Abstract

The synthesis of highly substituted naphthalenes from allylarenes and alkynes is described. This reaction proceeds via π-coordination of an allylic carbon–carbon double bond to the Pd(II) center and is followed by <i>ortho</i> selective C–H bond activation
