Nitrones. 7. .alpha.-Quinoxalinyl-N-substituted nitrone 1,4-dioxides
Journal of Medicinal Chemistry, 1977A series of alpha-quinoxalinyl-N-substitute nitrone 1,4-dioxides has been synthesize and evaluated as antibacterial and antiprotozoal agents. Structure-activity relationships are discussed. Of the compounds tested, alpha-(3-methyl-2-quinoxalinyl)-N-methylnitrone 1,4-dioxide (2) was the most active agent in vivo against the gram-negative and the gram ...

Cyclic nitrones. I. Reactions of α-keto nitrones at nitrone carbon
Australian Journal of Chemistry, 1967The chemistry of 3,4,5,6-tetrahydro-3-oxopyridine 1-oxides has been studied with respect to: reaction with hydrazine-the 6,6-dimethyl compound (IV) gave a hydrazone (VII) by ring contraction following initial attack at C 2; (ii)(ii) 2-arylation with diazonium salts, e.g. conversion of (III) into (XIII); (iii) acid- and base-catalysed deuterium exchange

Nitrones. Part III. Photolysis of cyclic nitrones
Journal of the Chemical Society C: Organic, 1966Ultraviolet irradiation of 2-substituted 1-pyrroline 1-oxides yielded corresponding bicyclic oxaziridines. Prolonged irradiation of the 3,3,5-trimethyl-6-oxa-1-azabicyclo[3,1,0]hexane gave an N-acetylazetidine and a pyrroline. Acid hydrolyses of 2,2,5- and 3,3,5-trimethyl-6-oxa-1-azabicyclo[3,1,0]hexane yielded acetonylacetone and 3,3-dimethylpentan-5 ...

Abstract Nitronic 20 was designed for elevated-temperature use where high mechanical strength and resistance to oxidation and sulfidation are important. This stainless steel exhibits high mechanical strength throughout the 1000-1700 F (538-927 C) temperature range, yet it is malleable at forging temperatures and provides excellent hot ...
