    • MacroModel® Program was the commercial version 7.0. Interatomic distances and angles were those of ref. 5. We were interested in this investigation by the ketopyrrole arm mobility governed by interactions in the 17, 18, 19, 20 part of the molecule, with or without a 19-Me group. Thus, in the model used for calculations, the mobile benzoxazole arm was replaced by a methyl group in 10eq position. OPLS-AA force field was used with conjugate gradient energy minimization to obtain the torsion angle versus energy plots represented in Fig. 2.
