Enolonium species, resulting from the umpolung of ketone enolates by Koser’s hypervalent iodine reagents activated by boron trifluoride, react with a variety of nitrogen heterocycles to form α-aminated ketones. The reactions are mild and complete in 4–5 h. Additionally, α-azidation of the enolonium species takes place using trimethylsilyl azide as a convenient source of azide nucleophile.
由Koser的由三氟化硼活化的高价碘试剂对酮烯醇化物进行封固而产生的olo烯类物质,与多种氮杂环反应形成α-胺化酮。反应温和且在4-5小时内完成。另外,使用三甲基甲硅烷基叠氮化物作为叠氮化物亲核试剂的方便来源,进行en物种的α-叠氮化。
