On August 13, 2012, Zhao, Hong-Wu; Li, Hai-Long; Yue, Yuan-Yuan; Qin, Xiao; Sheng, Zhi-Hui; Cui, Jin; Su, Shi; Song, Xiu-Qing; Yan, Hong; Zhong, Ru-Gang published an article.Safety of [2,2′-Bipyridine]-3,3′-diamine The title of the article was Design, synthesis and use of novel 3,3′-disubstituted 2,2′-bipyridine-based chiral ligands: asymmetric catalysis in direct aldol reactions. And the article contained the following:
A wide range of chiral ligands based on the 2,2′-bipyridine scaffold were designed and synthesized. In complexation with metal Lewis acids, the reactivity and stereoselectivity of the prepared chiral ligands were examined in asym. catalytic direct aldol reactions, thus providing the desired products with high stereoselectivities. The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Safety of [2,2′-Bipyridine]-3,3′-diamine
