the Special Topic Modern Strategies for Heterocycles Synthesis Abstract A cationic palladium(II) complex catalyzed reductive coupling of N-tosyl-tethered alkynones for the synthesis of functionalized piperidines was successfully developed. This reaction was initiated by hydropalladation of the alkyne and quenched by addition to the intramolecular carbonyl group. The substituent on the alkyne is key
作为“杂环合成的现代策略”专题的一部分发布 抽象的 成功开发了阳离子钯(II)络合物催化的N-甲苯磺酰基-链炔酮的还原偶联反应,以合成功能化的哌啶。该反应通过炔烃的加氢palpalpalation开始,并通过加到分子内羰基中止。炔烃上的取代基是反应的关键。 成功开发了阳离子钯(II)络合物催化的N-甲苯磺酰基-链炔酮的还原偶联反应,以合成功能化的哌啶。该反应通过炔烃的加氢palpalpalation开始,并通过加到分子内羰基中止。炔烃上的取代基是反应的关键。
