achiral chains containing up to three bipyridine units to various dissymmetric templates. Addition of copper(I) and silver(I) ions resulted in the highly stereoselective formation of bis(helicates), the absolute configuration of which was dictated by that of the templates, with (P) or (M) helicates being formed from (R) or (S) templates, respectively. In the cases of ligands containing three bipyridine
通过将含有多达三个联吡啶单元的两条非手性链连接到各种不对称模板上,已经获得了几种手性配体。铜(I)和银(I)离子的加入导致双(螺旋)的高度立体选择性形成,其绝对构型由模板的构型决定,(P)或(M)螺旋由(R或(S)模板。在含有三个联吡啶单元的配体的情况下,立体化学信息从模板转移到螺旋体上的距离约为20。
