The elucidation of the structure of a much more complicated molecule, naph-thomycinol (4), was reported by the same research group in late I996. The D-HMBC experiment was again used in conjunction with the conventional HMBC experiment. Correlations specifically noted in the report that were observed using the D-HMBC experiment correlated the 38-methyl resonance in the naphthoquinone portion of the molecule to the C25, C26. and C7 aromatic carbons via two- or three-bonds and via a " J correlation to the carbonyl at C23 in the ansa bridge resonating at 202.3 ppm. [Pg.51]
