Abstract

Three model amides (I-III) derived from 6-(N-alkylaminomethyl)-uracil and arylcarboxylic acids were synthesized and their conformation in solution studied. The 7-membered intramolecular hydrogen bond between amide carbonyl and H-N1 of uracil nucleus was proved to exist in solution of all three compounds using NMR and IR spectroscopy.
