A simple platform for carbocycle synthesis by Knoevenagel adduct deconjugative alkylation/Heck reaction is described. Deconjugative alkylation of Knoevenagels adducts is two-fold synthetically enabling because C–C bond formation is (1) operationally simple due to the ease of Knoevenagel adduct carbanion generation and (2) results in alkene migration, which poises the substrate for cyclization. Furthermore
描述了通过Knoevenagel加合物去共轭烷基化/ Heck反应合成碳环的简单平台。Knoevenagels加合物的去共轭烷基化有两个合成的可能,因为(1)由于Knoevenagel加合物的碳负离子易于产生,CC键的形成很简单,并且(2)导致烯烃迁移,这为环化反应提供了可能。此外,宝石-可降解部分用作合成操作的官能团。
