The ambivalent reactivity of 2-alkoxycarbonyl-substituted propargyl vinyl ethers has been explored. Depending on the conditions, the catalyzed and uncatalyzed Gosteli−Claisen rearrangement triggers downstream transformations that cascade from initially formed γ-allenyl α-keto esters to highly substituted furanes and cyclopentenes. In support of a mechanistic hypothesis, the results of a DFT study using
已经研究了2-烷氧基羰基取代的炔丙基乙烯基醚的二价反应性。根据条件的不同,催化的和未催化的Gosteli-Claisen重排触发下游转化,该转化从最初形成的γ-烯基α-酮酸酯到高度取代的呋喃和环戊烯级联。为了支持机械学说,揭示了使用B1B95和B3LYP功能的DFT研究的结果。
