Regio‐ and Stereoselective Olefination of Phenol Carbamates through C–H Bond Functionalization

Abstract

Abstract Two pathways that can be used to access ortho ‐olefinated phenol carbamate, including a ruthenium(II)‐catalyzed oxidative olefination of phenol carbamate with acrylates and a rhodium(III)‐catalyzed alkyne hydroarylation of phenol carbamate with internal alkynes through direct C–H activation, are reported. Both reactions afford substituted alkenes in a highly regio‐ and stereoselective manner.
