Furazans in Medicinal Chemistry

Journal of Medicinal Chemistry, 2021
Incorporation of heterocycles into drug molecules can enhance physical properties and biological activity. A variety of heterocyclic groups is available to medicinal chemists, many of which have been reviewed in detail elsewhere. Oxadiazoles are a class of heterocycle containing one oxygen and two nitrogen atoms, available in three isomeric forms ...

[Teratogenicity of 3, 4 two furazan-based oxidation furazan in rats].

Zhonghua lao dong wei sheng zhi ye bing za zhi = Zhonghua laodong weisheng zhiyebing zazhi = Chinese journal of industrial hygiene and occupational diseases, 2015
To study the teratogenicity of new high-energy compounds, 3, 4 two furazan-based oxidation furazan (DNTF) and the impact on human health, occupational exposure limits were provided for the following research.Pregnant SD rats were randomly divided into five groups by Standard teratogenicity test, including three dose groups (5.0, 15.8, 50.0 mg/kg), the ...

Furazans and furazan oxides. Part I. Synthesis and reactions of some strained furazan N-oxides

Journal of the Chemical Society, Perkin Transactions 1, 1972
Furazan N-oxides with a strained ring bridging the 3- and 4-positions are progressively deoxygenated by trialkyl phosphites, forming furazans, which can in some cases be isolated, and dinitriles. Heating in the presence of an acetylene forms bis(nitrile oxide) adducts (isoxazoles), with the more highly-strained types.

Gas-phase cyclodecomposition of furazane and furazane N-oxide

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1987
1. The thermal decomposition of furazane in the gas phase proceeds by a biradical mechanism with the nonsynchronous cleavage of the N-O and C-C bonds in the ring. 2. The gas-phase monomolecular cyclodecomposition of furoxane is facilitated by 4–6 kcal/mole and proceeds by a concerted mechanism.

The structures of furazans and furoxans

Chemistry of Heterocyclic Compounds, 1966
The IR spectra of furazans and furoxans are characterized by lowered values of frequencies and of integrated absorption band intensities for the C=N bands. The peculiarities of the UV absorption spectra of these compounds are similar to those of pyridine and its benzene analogs in comparison with the corresponding N-oxides.

Furazans and furazan oxides. 7. Interconversions of anthranils, benzofurazan oxides, and indazoles

The Journal of Organic Chemistry, 1977
7-Nitroanthranil (1, R = R = H) and 4-formylbenzofurazan oxide (2, R = R' = H) equilibrate on heating. The latter condenses with primary amines and the resulting imines rearrange to 7-nitroindazoles (8). The corresponding 6-methoxy and 6-chloro derivatives of 1 behave similarly.
