Metal-catalyzed borylative cyclization reactions of polyunsaturated compounds allow concomitant formation of C-C and C-B bonds to provide cyclic boronates, which constitute synthetically useful intermediates. Recent developments using first-row transition metals as catalysts provide fully atom-economical reactions that follow mechanisms involving σ-bond metathesis.
Keywords: boron; cobalt; cyclization; iron; metathesis.
