3-[(2-Hydroxyphenyl)amino]butanoic and 3-[(2-hydroxy-5-methyl(chloro)phenyl)amino]butanoic acids were converted to a series of derivatives containing hydrazide, pyrrole and chloroquinoxaline moieties. The corresponding benzo[b]phenoxazine derivatives were synthesized by the reaction of the obtained compounds with 2,3-dichloro-1,4-naphthoquinone. Five of the synthesized compounds exhibited good antimicrobial activity against Staphylococcus aureus and Mycobacterium luteum, whereas three compounds showed significant antifungal activity against Candida tenuis and Aspergillus niger.

5-Mercapto-3-(4′-pyridyl)-s-triazole (I; R = 4-pyridyl) reacts with alpha-halogenoketones to give 5-aroylmethylthio-3-(4′-pyridyl)-s-triazoles (IIa-f) which on treatment with PPA undergo cyclodehydration to furnish 5-aryl-3-(4′-pyridyl)thiazolo<2,3-c>-s-triazoles (IIIa-f) and not the isomeric 5-aryl-2-(4′-pyridyl)thiazolo<3,2-b>-s-triazoles (VIIIa-f).The structural assignments of III are based on elemental analyses, spectral data and the unequivocal synthesis of IIIa (R = 4-pyridyl; R1 = p-ClC6H4) by POCl3 cyclization of 4-(p-chlorophenyl)-2-isonicotinylhydrazinothiazole (V) obtained from isonicotinyl thiosemicarbazide (IV) and p-chlorophenacyl bromide.A similar condensation of I (R = 4-pyridyl) with 1,2-dibromoethane yields 5,6-dihydro-3-(4′-pyridyl)thiazolo<2,3-c>-s-triazole (VI) and not its isomer, 5,6-dihydro-2-(4′-pyridyl)thiazolo<3,2-b>-s-triazole (IX).This has also been proved by the unequivocal synthesis of VI by the reaction of IV with 1,2-dibromoethane.The reaction of I (R = 4-pyridyl) with 2,3-dichloroquinoxaline gives 3-(4′-pyridyl)-s-triazolo<3',4':2,3>thiazolo<4,5-b>quinoxaline (VII).

Several dyes derived from 5,12-dihydroquinoxalino[2,3b]quinoxaline have been synthesised and evaluated as sensitizers for alkoxypyridinium salt photodecomposition. The results are discussed on the basis of the free energy change for electron transfer from fluoflavin dyes to alkoxypyridinium compounds. The mechanism of dye photobleaching is supported by DFT calculations, spectroscopic characterization of the cation radical of the dye, and the quantum yields of sensitised proton formation. Fluoflavin dyes are shown to be useful as photoinitiators for sensitizing compounds to photooxidation. Photoredox pairs consisting of fluoflavin dyes and alkoxypyridinium salt are found to be effective initiation systems for free radical polymerization of methyl acrylate and trimethylolpropane triacrylate (TMPTA) using VIS light.

A series of eleven 1,4-dithiino[2,3-b]quinoxaline-2,3-dicarbonitriles was prepared by reaction of 2,3-dichloroquinoxalines with disodium (Z)-2,3-dimercapto-2-butenedinitrile in N,N-dimethylformamide. These products were tested for in-vitro fungicidal activity by a Minimum Inhibitory Concentration (MIC) method. Several of these compounds showed broad-spectrum fungicidal activity. The activity exhibited by these compounds was greatly dependent upon the substituents of the quinoxaline ring, with the nitro-substituted derivatives showing the higest levels of antifungal activity. None of the compounds prepared, however, showed fungicidal activity comparable to that of the commercial fungicides screened.
