摘要：
We present a mild and simple method for the cyclization of N-protected o-phenylenediamines with carbonyl compounds in the presence of trifluoroacetic acid. This method reliably provides various substrates of benzimidazoles and quinoxalin-2(1H)-ones, with all reactions conducted at room temperature, demonstrating excellent substrate adaptability and a broad substrate scope.
