Abstract

A simple method for the preparation of N-phenylbenzamides from azidobenzenes and 1,3-diphenylpropane-1,3-diones is described. In this reaction, N-phenylbenzamides were generated by [3+2] cycloaddition and intramolecular ring opening. The products were afforded in yields of 35–84% under mild conditions.

Abstract

A simple method for the preparation of 2-aryl-3-(2-aminoaryl)quinoxalines from 2-alkynylnitrobenzenes and 1,2-diaminoarenes was described. The reactions could proceed under mild conditions. The 1-nitro-2-(phenylethynyl)benzenes, simple starting materials, could generate the key intermediate 3H-indole-3-ones in situ in the presence of PPh3. After a cyclization with 1,2-diaminobenzenes, the 3H-indole-3-ones were then transformed into biologically valuable quinoxalines. [ABSTRACT FROM AUTHOR]
