In their report, 3-aminofurans are synthesized under Stetter conditions for coupling aromatic aldehydes with dimethyl acetylenedicarboxylate (DMAD), whereby the thiazolium ylide is hydrolyzed by the aromatization of the furan product.
In their study, 3-aminofurans are synthesized using Stetter conditions to link aromatic aldehydes with DMAD, and this process involves the breakdown of the thiazolium ylide through the formation of a furan compound.
