Thermolysis of ω-iodoalkyl-β-siloxyalkenenitriles in DMSO triggers an oxidative cyclization cascade that affords highly oxygenated hydrindanones, decalones, and undecanones. The cyclization cascade is highly unusual on three counts: the cyclization installs a contiguous array of tertiary–quaternary–tertiary centers, thermolysis equilibrates a quaternary center, and the enolsilyl ether crossed-aldol
DMSO 中 ω-碘代烷基-β-甲硅烷氧基烯腈的热解引发氧化环化级联反应,产生高度氧化的氢茚酮、癸酮和十一酮。环化级联在三个方面非常不寻常:环化安装了一系列连续的叔-季-叔中心,热解平衡了一个季中心,烯醇甲硅烷基醚交叉醛醇在没有催化剂的情况下进行。
