资源简介:
An exceptional oxone mediated tandem transformation of 2-aminobenzylamines to 2-substituted benzimidazoles is reported. It occurs at room temperature with aromatic, heteroaromatic, and aliphatic aldehydes. In this reaction initial condensation of 2-aminobenzylamine with appropriate aldehydes afforded a tetrahydro­quinazoline intermediate which underwent oxone-mediated ring distortion to afford the desired compounds in moderate to excellent yields.
