Rhodium‐Catalyzed Double 1,4‐Addition of Arylboronic Acids to β‐Aryloxyacrylates Involving β‐Oxygen Elimination

Abstract

Abstract The rhodium‐catalyzed addition reaction of arylboronic acids to β‐aryloxyacrylates gives 3,3‐diarylpropanoates in good yields. The double arylation reaction proceeds via the intermediate cinnamates generated by β‐oxygen elimination.
