金和环：金（I）催化的醛与1，6-烯炔的加成通过环加成/断裂过程得到1，3-二烯。1，5-烯炔通过5-endo-dig途径与醛和酮反应，得到相应的环加合物。
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.
