A concise synthesis of auxofuran (1) was developed. Starting with a Sonogashira cross-coupling reaction, enynol (10) was prepared. A gold(I) catalyzed cycloisomerization led to disubstituted furan ...

Gold(I)-catalyzed cycloisomerization of enynols 11 and 17, obtained by Sonogashira coupling, led to the tethered enoate-substituted furans 14 and 19. While attempts at thermal and several Lewis acid induced intramolecular Diels-Alder reactions remain
