Mandour, A. H.; Fathalla, O. A.; Basyouni, W. M. published an article in 2000, the title of the article was Synthesis of 2-(3-indolyl)-3,5-dihydro-[1,2,4]triazolo-[1,5-a]-5-pyridone and 2-pyridone derivatives.Recommanded Product: 75629-62-8 And the article contains the following content:
Indole-3-carboxaldehyde condensed with cyanoacetohydrazide to yield 3-indolylidinecyanoacetohydrazide (I). I condensed with different arylidenemalononitriles in presence of a base to give 7-aryl-6,8-dicyano-2-(3-indolyl)[1,2,4]triazolo[1,5-a]-pyridin-5-ones. Also, the condensation of I with different Et arylidenecyanoacetates gave the corresponding 4-aryl-3,5-dicyano-6-hydroxy-N-1-(3-indolylidine)pyridin-2-ones. The experimental process involved the reaction of 2-((1H-Indol-3-yl)methylene)malononitrile(cas: 75629-62-8).Recommanded Product: 75629-62-8
The Article related to indolyltriazolopyridinone preparation, triazolopyridinone indolyl preparation, Heterocyclic Compounds (More Than One Hetero Atom): Other 5-Membered Rings, Two Or More Hetero Atoms and other aspects.Recommanded Product: 75629-62-8
