An extension of the 'Bip method': induced axial chirality in a series of dipeptides based on Bip/β2,2-HBip combined with Ala/β3-HAla

Dipeptides based on β2,2-HBip/l(d)-Ala, Bip/l-β3-HAla, and β2,2-HBip/l-β3-HAla have been synthesized in solution and the induced circular dichroism in their biphenyl core has been evaluated.
