Optically active 2-amino-2'-diphenylphosphino-1,1'-binaphthyls having various functional groups, such as amino, alkoxycarbonylamino, acylamino, mono- and dialkylamino, and sulfonylamino at C2 position were prepared. The key intermediate of the above aminophosphines was 2-carbamoyl-2'-diphenylphosphinyl-1,1'-binaphthyl synthesized from optically active 2-cyano-2'-diphenylphosphinyl-1,1'-binaphthyl. The transformation of the carbamoyl group to an amino group was effected by the Hofmann reaction.Key words: aminophosphine ligand, Hofmann reaction, optically active phosphine ligand.
具有各种官能团的具有光学活性的2-氨基-2'-二苯基磷酰基-1,1'-联萘,例如氨基,烷氧羰基氨基,酰胺基,单烷基和双烷基氨基,以及C2位置的磺酰胺基被制备。上述氨基磷酸酯的关键中间体是由具有光学活性的2-氰基-2'-二苯基磷酰基-1,1'-联萘合成的2-氨基甲酰基-2'-二苯基磷酰基-1,1'-联萘。将甲酰基转化为氨基是通过Hofmann反应实现的。关键词:氨基磷酸酯配体,Hofmann反应,光学活性磷酸酯配体。
