Abstract

Ab-initio self-consistent field calculations are undertaken in order to investigate the possibilities for intramolecular hydrogen bonding in 2-aminomethyl-3-carboxymethyl pyrrole, an analog of porphobilinogen. The structure which features a hydrogen bond between the carboxyl hydrogen and the nitrogen of the aminomethyl substituent shows a decrease in energy of 4 kcal/mol compared to the most stable structure which does not exhibit such bonds.
