attention owing to their enormous synthetic potential in the preparation of a wide variety of
carbo-and heterocyclic building blocks.[1] Among them, goldcatalyzed cycloisomerization is
one of the hottest branches of research in the formation of functionalized cyclic structures.[2,
3] In particular, the cycloisomerization of enynes producing novel modes is one of the most
studied areas.[4] In research carried out in this field it must be taken into consideration that …
