摘要

The terphenyl structure has been proven to be an ideal scaffold mimicking side-chain functionalities of peptidic α-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 ...
