(1998)
The 1H and 13C NMR spectra of 2-phenyl-3H-naphtho[2,1-b][1,4]oxazin-3-one, 2-p-methoxyphenylnaphtho[1,2-d]oxazole and 2-phenylnaphtho[1,2-d]oxazole were totally assigned using a combination of one-and two-dimensional NMR ...
Structural and spectroscopic characterization of 2,2 `-methylenedi-8-quinolinol dihydrochloride dihydrate
(ELSEVIER SCIENCE BV, 2008)
The crystal structure of the title compound, a promising ligand for chelatoterapies in the treatment of Alzheimer`s disease, has been determined by single crystal X-ray diffractometry. The compound crystallized in the ...
Fevicordin A and Fevicordin A Glucoside, Novel Norcucurbitacins from Fevillea cordifolia

From the seeds of the Central American Fevillea cordifolia (Cucurbitaceae) fevicordin A glucoside (1) and fevicordin A (2) members of the novel norcucurbitacin group, were isolated.
Use of long-range C-H ((n)J n > 3) heteronuclear multiple bond connectivity in the assignment of the C-13 NMR spectra of complex organic molecules
(BENTHAM SCIENCE PUBL LTD, 2001-03)
The structural elucidation of complex organic molecules relies heavily on the application of proton detected heteronuclear NMR. Among these techniques, the HMBC NMR experiment is probably the most useful 2D NMR method The ...

Complete assignment of the 13C NMR spectra of a series of 5,8-disubstituted 4,4-dimethylanthracene-1,9,10(4h)-triones
(1999)
The regiosomeric quinones 5-acetyloxymethyl-4,4,8-trimethyl-(5) and 8-acetyloxymethyl-4,4,5-trimethylanthracene-1,9,10(4H)-trione (6) were synthesized and their regiochemistry was assigned on the basis of the unambiguous ...
Automated solvent artifact removal and base plane correction of multidimensional NMR protein spectra by AUREMOL-SSA
(Springer NetherlandsDordrecht, 2010-06)
Strong solvent signals lead to a disappearance of weak protein signals close to the solvent resonance frequency and to base plane variations all over the spectrum.
AUREMOL-SSA provides an automated approach for solvent ...
