Abstract

A general redox-neutral approach into the o-,o’-heteroatom-linked N-(hetero)aryl imidazole family of heteroaromatics has been developed. New types of heteroatom substituted carbimidoyl nitrenoids are efficiently realised from robust, bench-stable N-(heteroaryl) pyridinium N-aminides by formal gold-catalysed [3+2]-dipolar cycloadditions across ynamides. Broad structural variety and functional group tolerance allows rapid access into diverse functionalised scaffolds, as exemplified by the preparation of 8 different heteroaromatic cores.
