ChemInform Abstract: Highly Enantioselective Iridium-Catalyzed Hydrogenation of Cyclic Enamides

Autor: Xavier Verdaguer, Antoni Riera, Sílvia Orgué, Ernest Salomó

Publikováno v: ChemInform. 47

The MaxPHOX–Ir catalyst system provided the highest selectivity ever reported for the reduction of cyclic enamides derived from α- and β-tetralones. This result indicates that iridium catalysts are also proficient in reducing alkenes bearing meta
