A simple and convenient route for one-pot synthesis of cyclopenta[d]pyridazine through 1,3-dipolar cycloaddition of fulvenes and hydrazonyl chlorides is described. The reaction of fulvenes with hydrazonyl chlorides in the presence of silver carbonate smoothly afforded a series of cyclopenta[d]pyridazines.
描述了一种简单方便的途径,可通过富烯类化合物和肼基氯的1,3-偶极环加成反应一锅合成环戊[ d ]哒嗪。在碳酸银的存在下,富烯类化合物与肼酰氯的反应平稳地产生了一系列环戊[ d ]哒嗪。
