byproducts. Due to the inertness of the reaction byproducts, we found a one-pot transformation of the in situ generated silyl enol ethers into various α-functionalized carbonyls by reaction with Togni-II reagent or aldehydes.
通过用2,3,5,6-四甲基-1,4-双(三甲基甲硅烷基)-1,4-二氢吡嗪处理α-卤代羰基化合物来实现甲硅烷基烯醇醚的无盐立体选择性合成。在该反应中,产生易除去的三甲基甲硅烷基卤化物和2,3,5,6-四甲基吡嗪作为反应副产物。由于反应副产物的惰性,我们发现通过与Togni-II试剂或醛反应,将原位生成的甲硅烷基烯醇醚一锅转化为各种α-官能化羰基。
