Optically active 3,3'-dimethyl-2,2'-diamino-1,1'-binaphthyl (DM-DABN) and 3,3'-dimethyl-2-amino-2'-hydroxybinaphthyl (DM-NOBIN) derivatives were synthesized by Cu-(-)-sparteine complex-catalyzed enantioselective homo- and hetero-coupling of 2-naphthylamine, respectively. The difference in enantioselectivity was observed by changing the concentration of oxygen.
手性 3,3'-二甲基-2,2'-二氨基-1,1'-联萘(DM-DABN)和 3,3'-二甲基-2-氨基-2'-羟基联萘(DM-NOBIN)衍生物分别通过 Cu-(-)-sparteine 配合物催化 2-萘胺的对映选择性同偶联和杂偶联合成。通过改变氧气浓度观察到对映选择性的差异。
