denitrogenative [3+2] cycloaddition of 1‐sulfonyl‐1,2,3‐triazoles with cyclic silyl dienol ethers has been developed for the synthesis of functionalized hydroindolones or their corresponding silyl ethers. The present method has been employed to construct synthetically valuable bicyclo[3.3.1]alkenone derivatives and pyrrolidine‐ring‐containing bicyclic indole compounds. As a further synthetic application, a stereoselective
已开发了铑催化的1-磺酰基-1,2,3-三唑与环状甲硅烷基二烯醚的脱氮[3 + 2]环加成反应,用于合成官能化的氢吲哚酮或其相应的甲硅烷基醚。本方法已被用于构建具有合成价值的双环[3.3.1]烯酮衍生物和含吡咯烷环的双环吲哚化合物。作为进一步的合成应用,通过这种化学方法已实现了立体选择合成5,11-甲基吗啡啶-3-酮,该酮与褐煤型金莲花科生物碱具有关键骨架。
