Studies in benzofurans. Part X. Syntheses of some benzofuro[3,2-d]pyrimidines and benzofuro[3′,2′:4,5]pyrimidol[1,2-b]benzo[d]thiazole was written by Vaidya, V. P.;Agasimundin, Y. S.. And the article was included in Indian Journal of Chemistry in 1981.Computed Properties of C9H8N2O2 This article mentions the following:
Acylation of 3-aminobenzofuran-2-carboxamide using succinic, maleic and phthalic anhydrides followed by cyclodehydration of the resultant products I (R = CH2CH2CO2H, CH:CHCO2H, 2-HO2CC6H4 gives benzofuro[3,2-d]pyrimidines (II), which on further cyclodehydration furnish 2,3-dihydrobenzofuro[3,2-d]pyrrolo[1,5-a]pyrimidine-1,10-dione, benzofuro[3,2-d]pyrrolo[1,5-a]pyrimidine-1,10-dione, and benzofuro[3,2-d]isoindolo[1,7-a]pyrimidine-11,12-dione, resp. Reaction of ψ-saccharin chloride with 3-aminobenzofuran-2-carboxylic acid derivatives gave III and 7-oxobenzofuro[3′,2′:4,5]pyrimido[1,2-b]benzo[d]thiazole 5,5-dioxide (IV). In the experiment, the researchers used many compounds, for example, 3-Aminobenzofuran-2-carboxamide (cas: 54802-10-7Computed Properties of C9H8N2O2).
3-Aminobenzofuran-2-carboxamide (cas: 54802-10-7) belongs to benzofurans derivatives. Benzofurans are only weakly aromatic in nature and they are cleaved by many oxidative and reductive conditions. Benzofurans are stable towards alkali and readily polymerize on treatment with sulfuric acid, due to which they are useful for the preparation of low cost chemically relatively inert resins.Computed Properties of C9H8N2O2
