Rhodium-catalyzed ortho-acrylation of aryl ketone O-methyl oximes with cyclopropenones

Author affiliations

Abstract

An efficient Rh-catalyzed ortho-acrylation reaction for the synthesis of chalcones from O-methyl ketoximes and cyclopropenones via C–H bond activation has been described. This cross-coupling reaction exhibits high functional group tolerance and regioselectivity. A wide range of chalcone derivatives are obtained in moderate to good yields under mild conditions.
