Abstract

The effect of cyclization of the propionic acid residues in mesobilirubin XIII alpha propan-1,3-diyl ester on the angle between the dipyrrinone halves has been studied. This compound is shown to dimerize in chloroform solutions, and a conformation is proposed which is similar tothat of the corresponding dimethyl ester. The results point to the contribution of pi-pi interactions, besides hydrogen bonding, to the geometry of the dimer.
