An efficient rhodium/olefin–sulfoxide catalyzed asymmetric conjugateaddition of organoboronic acids to a variety of nitroalkenes has been developed, where 2-methoxy-1-naphthyl sulfinyl functionalized olefin ligands have shown to be highly effective and are applicable to a broad scope of aryl, alkyl, and heteroaryl nitroalkenes.

Old before I diene: An efficient rhodium/diene‐catalyzed asymmetricconjugateaddition of organoboronic acids to challenging nitroalkene substrates that lack α substituents has been developed. Chiral bicyclo[3.3.0] dienes were found to be superior ligands under ArB(OH)2/KHF2 conditions. Np=naphthyl.
