NUCLEAR MAGNETIC RESONANCE STUDY OF THE STRUCTURE OF GLYOXALDIHYDRAZONE
Study of the nuclear magnetic resonance spectra of glyoxaldihydrazone in dimethylsulfoxide and deuterochlorofonn leads to the conclusion that this compound exists predominantly in non-chelate structure
متن کاملComputational Investigation on Naphthoquinone Derivatives :Nuclear Magnetic Resonance (NMR) and Quantum mechanic
Naphthoquinones are natural aromatic compounds that can be discovered in various plant families. In recent times a diversity of biological activities of these compounds has been reported. In most cases, these pharmacological activities are related to redox and acid-base properties, which can be modulated synthetically by modifying the substituents attached to the 1, 4- naphthoquinone ring, in o...
متن کاملCarbon-13 nuclear magnetic resonance spectra of prostaglandins and some prostaglandin analogs.
High-resolution pulsed Fourier-transform nuclear magnetic resonance spectroscopy at 22.63 MHz was used to observe the proton-decoupled natural-abundance (13)C nuclear magnetic resonance spectra of CDCl(3) solutions of the methyl esters of prostaglandins F(1alpha), 15-epi-F(1alpha), F(2alpha), F(2beta), E(2), A(2), 13-dehydro-F(2alpha), 13-dehydro-F(3alpha), two intermediates on the synthetic pa...
متن کامل13C-nuclear magnetic resonance investigations of xanthine and some of its N-methylated derivatives.
The 13C-Nuclear Magnetic Resonance spectra of xanthine, 1,3-dimethyl-xanthine (theophylline), 3,7-dimethyl xanthine (theobromine) and 1,3,7-trimethylxanthine (caffeine) were obtained and the lines assigned. Protonationand N-Methylation parameters are derived by comparison of the 13C-chemical shifts of the protonated cations with those of the neutral molecules and also with those of the xanthine...
متن کاملTwo-dimensional nuclear magnetic resonance spectra of selected tricyclic antidepressants.
Two-dimensional nuclear magnetic resonance (2D NMR) spectroscopy has been used to assign 13C spectra of the tricyclic antidepressants imipramine and chlorimipramine . The 2DINADEQUATE method was used to unambiguously assign the aromatic spectral region for the former compound. Errors in previous literature assignments based on 1D methods were corrected. For chlorimipramine the pitfalls of class...
