Cascade synthesis of fenpiprane and related pharmaceuticals via rhodium-catalyzed hydroaminomethylation

Li, Shengkun,Huang, Kexuan,Zhang, Jiwen,Wu, Wenjun,Zhang, Xumu

, p. 1036 - 1039 (2013)

A novel rhodium catalytic system with Naphos as ligand was developed for an efficient hydroaminomethylation of 1,1-diphenylethene under relatively mild conditions. This will allow for an atom-economic and environmentally benign synthesis of fenpiprane and related pharmaceuticals.
