Eight conformers typical of diketopiperazine (DKP) ring folding were chosen for analysis. Conf~ormational energy calculations were carried out using the semiempirical quantummechanical CNDOI:! method. The results obtained confirm considerable flexibility of'the IIKP skeleton. As the degree of' fold
