An Attempt to Assign the NMR Spectra in 7-Methyl- and 7-Benzyl-substituted 7H-Purine 1-Oxides Using the ACD/Labs Software Package
نویسنده
چکیده
Commercially available 4-nitroimidazole can be transformed in a few simple steps into 4-aminoimidazoyl-5-carboximes, from which the respective purine mono-1-oxides may be synthesized. The N→O functionality in these products significantly changes the electron density in the purine skeleton and consequently, the determination of the Hand C-NMR spectra of these simple compounds is somewhat troublesome. The use of the ACD/Labs software package for this purpose is discussed.

Background and purpose: Despite growing list of antifungal agents, their clinical value has been limited by their relatively high risk of toxicity, the emergence of drug resistance, and insufficiencies in their antifungal activity. This situation has led to an ongoing search for potent broad spectrum antifungal agents with low side effects, which can be administered both orally and parenteral...

متن کاملUsing Implicit/Explicit Salvation Models to Theoretical Study Tautomerism in 7H-purine-2, 6-diamine
A theoretical study at the B3LYP/6-31++G(d,p) level was performed on the tatumerization of 7H-purine-2, 6-diamine into 9H-purine-2, 6-diamine. Such a tautomerism can take place via three different pathways namely A, B, and C. The energetic results associated with the gas phase reveal that pathways A, B, and C display a very high activation Gibbs free energy of 45.1, 68.6 and 48.9 kcal/mol, resp...
