Nitrogen-15 NMR spectroscopy. Part X. Nitrogen-15 NMR spectra of azoles with two heteroatoms was written by Chen, Ban Chin;Von Philipsborn, Wolfgang;Nagarajan, Kuppuswamy. And the article was included in Helvetica Chimica Acta in 1983.Related Products of 5765-44-6 This article mentions the following:
The 15N-NMR spectra of azoles, with natural isotope abundance, have been measured under different exptl. conditions, and chem. shifts are reported for imidazoles, pyrazoles, oxazoles, isoxazoles, thiazoles, and isothiazoles. General trends of substituent effects in this heterocyclic series are discussed based on the data of 67 substituted azoles, dihydro- and tetrahydroazoles. 15N, 1H spin-coupling constants have been determined from spectra obtained by [1H] → 15N polarization-transfer experiments, i.e. an application of INEPT and DEPT pulse sequences. Two-bond and three-bond coupling constants are fully assigned and are discussed in terms of the specific pathways in azoles. The potential of structural applications of the new data is illustrated for isomeric nitro-imidazoles and highly-substituted pyrazoles, and in the case of ring-chain tautomerism of 2-substituted tetrahydrooxazoles. In the experiment, the researchers used many compounds, for example, 5-Methylisoxazole (cas: 5765-44-6Related Products of 5765-44-6).
5-Methylisoxazole (cas: 5765-44-6) belongs to isoxazole derivatives. Isoxazole rings are found in some natural products, such as ibotenic acid and muscimol. Isoxazole can be synthesised via a variety of methods. Examples include via the reaction of hydroxylamine with 1,3-diketones or derivatives of propiolic acid.Related Products of 5765-44-6
