摘要
Ammonium carbamate can be used as a very effective reagent for preparation of 2,4,6-triarylpyridine derivatives from ring transformation of pyrylium salts under solvent-free conditions. The products are isolated without aqueous work-up in high purity and good yields. The microwave accelerated the reaction and renders the whole synthesis into a truly eco-friendly protocol.
