A novel tandem reaction by combination of Diels–Alder [4+2] cycloaddition and [3+2] IMCC (intramolecular cross-cycloaddition) of dienylcyclopropane 1,1-diesters has been successfully developed. In this reaction, three new rings and four new stereocenters were generated in one-pot. This supplies a strategy for rapid construction of 6,6- and 6,7-fused carbocyclic skeletons which are common cores in
通过 Diels-Alder [4+2] 环加成和 [3+2] IMCC(分子内交叉环加成)组合的二烯基环丙烷 1,1-二酯的新型串联反应已成功开发。在该反应中,一锅法生成了三个新环和四个新立体中心。这为快速构建 6,6- 和 6,7-稠合碳环骨架提供了一种策略,这些骨架是许多具有生物学重要意义的天然产物的共同核心。
