Gold-Catalyzed Cycloisomerization of (2-Alkynyl-1-cycloalkenyl)methanols to Highly Substituted Furans

摘要

A new and efficient Au-catalyzed alkoxycyclization of conjugated enynols offers a general entry to a wide range of highly substituted furans in good to excellent yields. These furans were subjected to diethyl acetylenedicarcoxylate to afford the interesting cycloadducts in good to excellent yields.
