An exceptional intramolecular palladium-catalyzed alkenylation of silyl enol ether in the absence of a fluoride additive was developed, and this reaction led to the construction of bicyclo[3.3.1]nonane ring system in reasonable yield. In this type of reactions, trialkylamines were employed as additives instead of previously indispensable fluoride additives.
在没有氟化物添加剂的情况下,开发了一种特殊的分子内钯催化的甲硅烷基烯醇醚的烯基化反应,该反应导致以合理的收率构建了双环[3.3.1]壬烷环系统。在这种类型的反应中,三烷基胺被用作添加剂,而不是先前必不可少的氟化物添加剂。
