The formation of S-nitrosoglutathione (GSNO) from amyl nitrite and n-butyl nitrite was studied in rat liver microsomes, employing N-ethylmaleimide (MalNEt) as an activator and indomethacin as an inhibitor of microsomal glutathione S-transferase (GST). Rates were compared with GST activity measured with 1-chloro-2,4-dinitrobenzene (CDNB) as a substrate. MalNEt stimulated GST activity and the for...

Alkyl nitrites have been problematic worldwide due to their recreational use. Although there is a lack of scientific information on their action on the central nervous system (CNS), many anecdotal reports and case studies have inferred the CNS actions of alkyl nitrites. The objective of this study was to investigate the effects of alkyl nitrites on the CNS, especially focusing on the dopaminerg...

A simple and efficient catalytic system for direct conversion of methylarenes into aromatic oximes has been developed, with Cu(OAc)2 as catalyst, NHPI (N-Hydroxyphthalimide) as additive, TBN (tert-butyl nitrite) as both the nitrogen source and the oxidant. This process proceeds under mild conditions, tolerates a wide range of substrates, affording the targeted aromatic oximes in 63-86% yields.

We describe here a new metal-free route for the synthesis of 3-nitroindoles by the nitrative cyclization of N-aryl imines with tert-butyl nitrite. The radical transformation allows the assembly of the indole framework through oxidative cleavage of multi C-H bonds, a nitration, cyclization and isomerization cascade.

We report on the photodissociation dynamics study of n-butyl nitrite and isoamyl nitrite by means of time-resolved Fourier transform infrared (TR-FTIR) emission spectroscopy. The obtained TR-FTIR emission spectra of the nascent NO fragments produced in the 355 nm laser photolysis of the two alkyl nitrite species showed an almost identical rotational temperature and vibrational distributions of ...

Aryl-substituted olefins react with t-butyl nitrite and sodium borohydride in the presence of iron(ii)phthalocyanine to give oximes in moderate to high yields.

In the case of the nitrosation of the methyl or ethyl group of carbonyl compounds, such as acetone and 2-butanone, the E-form of the hydroxyimino compound was predominantly obtained. On the other hand, a E-form/Z-form (E/Z) ratio of 2.3 was observed for the nitrosation of 3-methyl-1phenylbutan-1-one (PhCOCH2CH(CH3)2) (5) with tert-butyl nitrite in THF. Thus the E/Z ratio decreased with increasi...
