Abstract
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.
摘要
金与环
金（I）催化醛与1,6-烯炔加成通过环加成/碎片化过程生成1,3-二烯。1,5-烯炔通过5-内型-亲核环化途径与醛和酮反应生成相应的环加成产物。
