Base-promoted aerobic oxidative synthesis of fused 1,3,5-triazines under metal-free conditions†
Abstract
An efficient base-promoted aerobic oxidation reaction for the synthesis of fused 1,3,5-triazines from 2-aminobenzimidazoles, aromatic aldehydes, and ammonium iodide has been developed. In this multi-component protocol, ammonium iodide served as a convenient nitrogen source and four C–N bonds were formed in one pot under metal-free conditions.
