Abstract
Optically active 2-amino-2'-diphenylphosphino-1,1'-binaphthyls having vario us functional groups, such as amino, alkoxycarbonylamino, acylamino, mono- and dialkylamino, and sulfonylamino at C2 position were prepared. The key i ntermediate of the above aminophosphines was 2-carbamoyl-2'-diphenylphosphi nyl-1,1'-binaphthyl synthesized from optically active 2-cyano-2'-diphenylph osphinyl-1,1'-binaphthyl. The transformation of the carbamoyl group to an a mino group was effected by the Hofmann reaction.
