Abstract: An efficient method for the synthesis of 1,4-ketoaldehydes via the cross-coupling of N-alkenoxyheteroarenium salts and primary aldehydes is developed. This method provides a broad substrate scope and excellent functional group compatibility. The utility of this… read more here.

Abstract: α-Halo borides are generally constructed via Matteson homologation, and the synthesis of both fluorinated and functionalized ambiphilic boronates is challenging and has received inadequate attention. Herein, we describe the N-methyliminodiacetyl boronate [B(MIDA)]-directed halogenation of alkenes… read more here.
