Abstract
An analysis of 11 crystal structures of cyclic dipeptides so far reported in the literature is made, with main reference to the internal parameters of these molecules. Preferred conformations of the side chains of cyclic dipeptides with different α‐amino acid residues have been studied by classical energy calculations. The possible conformations of the DKP ring are also studied. The significance of the non‐bonded interaction in deciding the pathway for conformational change has also been investigated. The agreement between theoretical results and experimental observations is quite good, both with respect to the conformation of these molecules as well as the enthalpy difference as estimated from n.m.r. studies between different conformers.This publication has 21 references indexed in Scilit:
