Trofimov, F. A. et al. published their research in Khimiya Geterotsiklicheskikh Soedinenii in 1975 | CAS: 54802-10-7

3-Aminobenzofuran-2-carboxamide (cas: 54802-10-7) belongs to benzofurans derivatives. Benzofuran derivatives are one of the most important oxygen-containing heterocycles. Introduction of benzofurans in organic synthesis, particularly drug synthesis, involves generally the use of their metalated species as nucleophiles in addition reactions or in metal-catalysed cross-coupling reactions.COA of Formula: C9H8N2O2

2-Acyl-3-aminobenzofurans. II. Synthesis of heterocyclic systems consisting of 2-acyl-3-aminobenzofuran derivatives was written by Trofimov, F. A.;Shevchenko, L. I.;Lelyak, G. F.;Grinev, A. N.. And the article was included in Khimiya Geterotsiklicheskikh Soedinenii in 1975.COA of Formula: C9H8N2O2 This article mentions the following:

Cyclization of I (R = Ac, R1 = OH) by Ac2O gave 87% benzofurooxazine II; cyclization by PhNH2 gave 54% III (R = Me, R1 = Ph). Treatment of I (R = H, R1 = OMe) with CH(OEt)3 gave 15% III (R = R1 = H); treatment with O-methylcaprolactam gave 35% III [RR1 = (CH2)5]. Treatment of I (R = ClCH2CO, R1 = Ph) with urotropine gave IV. In the experiment, the researchers used many compounds, for example, 3-Aminobenzofuran-2-carboxamide (cas: 54802-10-7COA of Formula: C9H8N2O2).
