Reactivity of N-(4-Nitrophenyl)propionohydrazonoyl Bromide. Synthesis and Antimicrobial Study of Thiadiazoles and 4,6-Dithia-1,2,9-triazaspiro-[4.4]-non-2-en-8-ones was written by Mohamed Teleb, Mohamed A.;Kamel, Monica G.;Ead, Hamed A.;Hassaneen, Hamdi M.;Saleh, Fatma M.. And the article was included in Polycyclic Aromatic Compounds.Quality Control of 6,7-Dimethoxy-3,4-dihydroisoquinoline This article mentions the following:
Treatment of thioanilides with N-(4-nitrophenyl)propionohydrazonoyl bromide in refluxing chloroform in the presence of triethylamine gave thiadiazoles. Stirring of 2-((methylthio)carbonthioyl)hydrazonoes with hydrazonoyl bromide in ethanol in the presence of triethylamine at room temperature afforded the corresponding thiadiazole derivatives Also, reaction of 5-arylidene-3-phenyl-2-thioxothiazolidin-4-ones and hydrazonoyl bromide in chloroform in the presence of triethylamine at reflux to yield the corresponding 4,6-dithia-1,2,9-triazaspiro[4.4]non-2-en-8-one derivatives The structures of the latter new products were identified by elemental anal. and spectral data. Antimicrobial studies were performed against all synthesized compounds Compounds , , and were exhibited high antimicrobial activities against the tested microorganisms. The other compounds showed no activities. In the experiment, the researchers used many compounds, for example, 6,7-Dimethoxy-3,4-dihydroisoquinoline (cas: 3382-18-1Quality Control of 6,7-Dimethoxy-3,4-dihydroisoquinoline).
6,7-Dimethoxy-3,4-dihydroisoquinoline (cas: 3382-18-1) belongs to isoquinoline derivatives. Quinoline is a mancude organic heterobicyclic parent, an azaarene, an ortho-fused heteroarene and a member of isoquinolines. Lewis acid activation and nucleophilic attack can produce multiple regioisomers in quinolines and pyridines; isoquinolines generally only undergo attack at the 1-position.Quality Control of 6,7-Dimethoxy-3,4-dihydroisoquinoline
