Oxygen-17 nuclear magnetic resonance study of some five-membered heterocyclic derivatives was written by Chimichi, Stefano;Nesi, Rodolfo;De Sio, Francesco. And the article was included in Organic Magnetic Resonance in 1984.Recommanded Product: 5765-44-6 This article mentions the following:
17O NMR spectra were obtained in the Fourier-transform mode for some furan and isoxazole derivatives The chem. shifts, mainly governed by the electronegativities of the atoms bonded to the central O, are also affected by alkylation on the different positions of the ring systems, which gives rise to β and γ effects similar to those observed for simple aliphatic ethers. In the experiment, the researchers used many compounds, for example, 5-Methylisoxazole (cas: 5765-44-6Recommanded Product: 5765-44-6).
5-Methylisoxazole (cas: 5765-44-6) belongs to isoxazole derivatives.Synthetically, isoxazoles serve as valuable precursors for the construction of diverse molecules, including many natural products. As with isoxazolines, isoxazoles may be cleaved using low-valent titanium obtained from the Kulinkovich reaction.This procedure affords enaminoketones from 2,4-substituted isoxazoles.Recommanded Product: 5765-44-6
