3-dioxepin derivatives, two of which also had a carbonyl function in one of their 2-R groups, were prepared and reacted with dimethyl diazomalonate with copper(II) acetylacetonate as a catalyst. Ylide formation probabilities with allyl ether and/or carbonyl functions were investigated. A chemoselectivity in favor of carbonyl ylide was observed.
制备了一系列的2-单-和2,2-二取代的1,3-二氧杂戊环衍生物,其中两个在其2-R基团中也具有羰基官能团,并与重氮丙二酸二甲酯与乙酰丙酮铜(II)反应作为催化剂。研究了具有烯丙基醚和/或羰基官能团的叶立德形成概率。观察到有利于羰基叶立德的化学选择性。
