Gold and rings: The gold(I)‐catalyzed addition of aldehydes to 1,6‐enynes gives 1,3‐dienes, by a cycloaddition/fragmentation process. 1,5‐Enynes react with aldehydes and ketones by the 5‐endo‐dig pathway to give the corresponding cycloadducts.
金和环:通过环加成/片段化工艺,金(I)催化的醛加成到1,6-炔烃中得到1,3-二烯。1,5-烯炔通过5-内切酶途径与醛和酮反应,生成相应的环加合物。
