Application of 3889-13-2, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 3889-13-2, 5-Nitro-2,3-dihydro-1,3-benzoxazol-2-one, introducing its new discovery.
Synthesis of Substituted 2-Phenylbenzoxazoles as CNS Active Agents
The reaction of hydrazine (III) with CS2 and ethanolic KOH furnishes 2-<2'-(benzoxazolyl)phenoxymethyl>-5-mercaptooxadiazole (IV) which on Mannich reaction with piperidine and morpholine gives the bases Va and Vb respectively.Condensation of isatin and 5-chloroisatin with III affords VI and VII which on Mannich reaction furnish the bases VIII and IX respectively.Condensation of N-methylisatin and N-methyl-5-chloroisatin with III gives X and XI.Treatment of 2-(p-hydroxyphenyl)benzoxazole (I) with allyl bromide furnishes the allyl derivative (XII) while acetylation of it with Ac2O gives XIII.Mannich reaction of benzothiazolin-2-thione, benzoxazolin-2-one and 6-nitrobenzoxazolin-2-one with 2-(p-aminophenyl)benzoxazole (XIV) affords the compounds XV, XVIa and XVIb, respectively.Treatment of acetanthranil (XVII) with XIV gives 3--2-methyl-4-quinazolone (XVIII).Condensation of isatin and N-methylisatin with XIV furnishes XIX and XX respectively.The former (XIX) on Mannich reaction with morpholine and formaldehyde gives rise to XXI.
