Notes:
The pi interaction in complexes of (S)-methyl N-(2-naphthyl)alaninate with (S)- and (R)-N-(3,5-dinitrobenzoyl)leucine n-propylamide was investigated with Hartree-Fock and second-order Møller-Plesset perturbation theory calculations using the STO-3G basis set. For each complex, the geometry of the model of the pi interaction (i.e., naphthalene and 1,3-dinitrobenzene) was derived directly from the complex geometry which was relaxed by the semiempirical quantum-mechanical AM1 method. At the level of treatment used herein, our results are in agreement with our earlier AM1 interaction energy calculations in which the pi interaction, one of the three primary interactions proposed in models of the aforementioned complexes, is attractive and of equal strength (ca. 0.8 kcal/mol) in both complexes.
