Cyclocondensation reactions of heterocyclic carbonyl compounds. I. Synthesis of some 6-substituted 2,3-dihydro-5H-1,2,4-triazino[5,6-b]indole-3-thiones was written by Hlavac, Jan;Slouka, Jan. And the article was included in Acta Universitatis Palackianae Olomucensis, Facultas Rerum Naturalium in 1993.Category: indole-building-block This article mentions the following:
Condensation of 7-nitroisatin and 7-methylisatin with thiosemicarbazide in acetic acid gave the corresponding 闁?thiosemicarbazones. These 闁?thiosemicarbazones were converted into 1,2,4-triazino[6,5-b]indole-3-thiones I (R = NO2, Me). In the experiment, the researchers used many compounds, for example, 7-Nitroindoline-2,3-dione (cas: 112656-95-8Category: indole-building-block).
7-Nitroindoline-2,3-dione (cas: 112656-95-8) belongs to indole derivatives. The indole subunit is an almost ubiquitous component of biologically active natural products, and its study has been the focus of research for decades. In addition to indole, the strain-release chemistry worked for numerous substrates including amines, alcohols, thiols, carboxylic acids, imidazoles, and pyrazoles.Category: indole-building-block
