Simple allenyl ethers have been shown to be efficiently activated by cationic gold(I) catalysts to form reactive dienophiles in intermolecular Diels–Alder reactions. A range of different dienes give the cycloaddition products in moderate to excellent yields and good selectivity.
简单的烯基醚已被阳离子
金(I)催化剂有效活化,在分子间Diels-Alder反应中形成反应性亲二烯体。一系列不同的二烯使环加成产物的产率中等至优异,并且具有良好的选择性。
