We report here the synthesis of a series of imidazolinylhydrazones of salicylaldehyde and their substituted 2-N-tosylaminobenzaldehyde, 2-diphenylphosphinobenzaldehyde, and diacetylmonooxime derivatives, as well as the bis-imidazolinylhydrazones of 2,6-diformyl-4-tert-butylphenol and 2,6-diacetylpyridine. The protistocidal and antibacterial activities of(More)
New 1-(2-aryloxyethyl- and 2-halobenzyl)-3-(2-hydroxyethyl)-2-imino-1,3-dihydrobenzimidazoline hydrochlorides were synthesized via reactions of 1-(2-aryloxyethyl- and 2-halobenzyl)-2-aminobenzimidazoles with ethylenechlorohydrin. These compounds were shown to possess both bactericidal activity against some pathogenic Gram-positive and Gram-negative bacteria(More)
9-Bromocotarnine in the stable perchlorate form has been obtained by the interaction of cotarnine with bromine. The reaction of 9-bromocotarnine with α-haloketones is accompanied by the extension of the six-membered hetero-ring to seven-membered ring and led to previously unknown(More)
Reaction of 9-bromocotarnine with heterocyclic α-halo ketones is accompanied by the expansion of the six-membered dihydropyridine ring to seven-membered dihydroazepine one and leads to previously unknown 4-heteroaroyl-9-bromo-3-methyl-1,2-dihydro-6-methoxy-7,8-methylenedioxy-3-benzazepines. It has been shown that some of the resulting compounds exhibit a(More)
Previously unknown 1-alkyl-, 1-benzyl-, and 1-aryloxyethylderivatives of dichloroimidazoles and products of their structural transformation were synthesized from 4,5-dichloroimidazole or 2-methyl-4,5- dichloroimidazole using alkyl, benzyl or aryloxyethyl halides. These N-substituted compounds were shown to have a weak antibacterial activity against some(More)
Previously undescribed 2-, 4or 6-substituted hetaryl-3(5)-nitropyridines were synthesized by the interaction of a number of chlorosubstituted 3(5)-nitropyridines with some diazoles or 3-chloropyridazin-6one. In addition, pyrazolyl-3-nitropyridines were prepared by both the above method and cyclization of hydrazinopyridines, which, in turn, were synthesized(More)
Alkylation of 2-aminobenzimidazole by methyliodide and benzyl- or 2-aryloxyethylbromides produced 1-substituted 2-aminobenzimidazoles that were quaternized by chloroacetamide to previously undescribed 3-aryloxyethyl(benzyl)-1-carbamoylmethyl-2-iminobenzimidazoline hydrochlorides. These compounds were shown to possess antibacterial activity against several(More)
