Complete assignment of the 'H and I3C NMR spectra of flavone and three flavone derivatives is reported. Protonproton and carbon-proton coupling constants of the flavones, including the extreme seven-bond long-range coupling between H-7 and H-3 in 6-hydroxyflavone (0.52 Hz) and flavone (0.27 Hz), are

13C NMR spectra of free bleomycin A, at pH 4 and 6.7 and of its zinc complex at pH 6.7 were completely assigned by making use of two-dimensional 'H-"C correlated spectroscopy. Differences in resonance positions between the spectra of the free bleomycin at pH 4 and 6.7 are observed for the /?-hydroxy
The total assignment of the 13C and the ' H NMR spectra of four derivatives of 1,3diaza-2,4-diboranaphthalene has been performed. The interpretation of the spectra was achieved from the concerted application of direct and long-range heteronuclear chemical shift correlation and homonuclear COSY two-d
## Abstract The ^1^H NMR spectra of naphthalene as an eight spin system, and two of its derivatives, 2,4βdichloroβ and 2,4βdinitroβ1βnaphthol, have been completely analysed. The Indor technique has been very useful in the determination of the signs and magnitudes of very small coupling constants. A
In the course of our studies on the synthesis of anthracyclines [I-41 based on the Diels-Alder additions of exocyclic s-cis-butadiene moieties grafted onto 7-oxabicyclo[2.2. Ilheptane derivatives 1, we observed 'H-NMR spectra of the corresponding adducts 2 with measurable homoallylic 'J(H,H) couplin
