New Quinazolin-4(3H)-One Derivatives Incorporating Isoxazole Moiety as Antioxidant Agents: Synthesis, Structural Characterization, and Theoretical DFT Mechanistic Study

Pharmaceuticals
Background: This research centers on the development and spectroscopic characterization of new quinazolin-4(3H)-one-isoxazole derivatives (5a–e). The aim was to investigate the regioselectivity of the 1,3-dipolar cycloaddition involving arylnitriloxides ...

Aromaticity and tautomerism-VII1 1 Part VI see M.J. Cook. A.R. Katritzky, A.D. Page, R.D. Tack and H. Witek, Tetrahedron 32,1773 (1976). Empirical resonance energy and conjugation energy of pyrazole and isoxazole from heats of dehydration data

, 1978
The dehydration of various 4,5-dihydro-4- and -5-hydroxy derivatives of pyrazole and isoxazole has been investigated. Heats of dehydration of 4,5-duiydro-4-hydroxy-1,3,5-tripbenylpyrazole and 4,5-dihydro-5-hydroxy-isoxazole are evaluated and used to ...

Reactions of an imidazo[4,5-c]isoxazole-6-carboxylate with dimethyl acetylenedicarboxylate; formation of the first example of a [1,4]diazepino[2,3-c]isoxazole

, 2000
The synthesis of the first example of a [1,4]diazepino[2,3-c]isoxazole derivative is reported. Reaction of an imidazo[4,5-c]isoxazole with acetylenic esters has been shown to lead to the formation of 2-pyrrol-2-yl imidazoles, Here we report an alter ...

Clicking towards sustainability : synthesis of poly(isoxazole)s from biomass via nitrile oxide/yne polymerisation [PDF]

Click chemistry has been a reliable, selective, and simple synthetic method for incorporating heteroatoms in polymer chemistry and material science. Poly(isoxazole)s can be prepared by the polycycloaddition of two clickable monomers, such as nitrile ...
