Abstract
The ^1^H and ^13^C chemical shifts, proton‐proton coupling constants, and one‐bond carbon‐hydrogen coupling constants have been obtained for 7‐azaindole, 1‐methyl‐7‐azaindole, their corresponding methyl iodide salts, and the related compound 7‐methyl‐7__H__‐pyrrolo [2,3‐b]pyridine. are different from those of either 7‐azaindole or 1‐methyl‐7‐azaindole.

## Abstract The ^13^C chemical shifts and one‐bond carbon‐hydrogen coupling constants have been obtained for some hydroxycoumarins and their corresponding acetoxy and methoxy derivatives. The changes in the one‐bond carbon‐hydrogen coupling constants resulting from the conversion of a hydroxy group
One-bond and long-range two-dimensional 1 H and 13 C NMR experiments and deuterium-induced 13 C isotope shifts n C(ND) allow the unequivocal assignment of 13 C and 1 H spectra. On this basis, previous assignments of biologically active nifedipine, nicardipine and related compounds have been revised
Proton and carbon-13 spectra of benzyl compounds of the general formula (C,H,CH,),X with a large variety of X substituents have been measured. While a linear relationship between the CH, chemical shift and the substituent electronegativity was found both for lH and lac, large deviations from lineari
## Abstract The ^13^C n.m.r. spectrum of benzofuroxan at −15°C is assigned on the basis of selective decoupling experiments and by comparison with the ^13^C chemical shifts of model compounds. The ^13^C spectra were also measured in trifluoroacetic acid as a solvent. From the temperature dependence
## Abstract This article presents the structure elucidation of four new compounds, formed during the hemisynthetic preparation of trabectedin, an anti‐tumor natural product from __Ecteinascidia turbinata__. We report herein on the use of UV, MS and NMR spectroscopic data along with ^1^H and ^13^C s
