Nitrones. 7. .alpha.-Quinoxalinyl-N-substituted nitrone 1,4-dioxides

Journal of Medicinal Chemistry, 1977
A 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 ...

Correlation between structure and stability of nitronic acids and nitronic esters

Science in China Series B: Chemistry, 1998
On the basis of investigation on structural characteristics and stability of more than one hundred nitronic acids and nitronic esters, an equilibrium theory of electronic effects in conjugated systems is put forward and the type of structures is classified. On that basis, an empirical rule for the correlation between structure and stability of nitronic

Reactivity of Morita-Baylis-Hillman Adducts in C-H Functionalization of (Hetero)aryl Nitrones: Access to Bridged Cycles and Carbazoles.

Organic Letters, 2018
The rhodium(III)-catalyzed cross-coupling of (hetero)aryl nitrones with Morita-Baylis-Hillman (MBH) adducts is described. An allylated intermediate derived from aryl nitrones and MBH adducts allows the formation of bridged cyclic compounds via an exotype
