title: Full assignments of the 1H, 13C and 15N magnetic resonance spectra of two porphyrin compounds.
abstract: Two chlorin derivatives, rhodochlorin dimethyl ester (7) and chlorin-e6 trimethyl ester (8), were prepared from methyl pheophobide a (6) through base-degradation of the E ring and methylation of the carboxylic acids. Full assignments of the 1H, 13C and 15N magnetic resonance spectra of compounds 7 and 8 were made by 2D NMR techniques (1H-1H COSY, 1H-13C HMQC, 1H-13C HMBC, 1H-15N HMBC).
