side-chain functionalities of peptidic alpha-helices. The synthesis of 1,4-dipiperazino benzenes, using stepwise transition metal-catalyzed N-arylation of chiral piperazines to a central benzene core is reported. The structure determination by X-ray crystallography reveals a geometrical arrangement of the hydrophobic side chains resembling the orientation of key i, i + 3, and i + 7 positions in a peptidic
已证明三联苯结构是模仿肽α-螺旋的侧链功能的理想支架。报道了使用手性哌嗪的逐步过渡金属催化的N-芳基化至中心苯核的合成1,4-二哌嗪基苯。通过X射线晶体学确定的结构表明,疏水性侧链的几何排列类似于肽α-螺旋或三联苯螺旋模拟物中关键i,i + 3和i + 7位置的方向。
