A palladium-catalyzed domino Heck/intermolecular direct hetero arylation sequence of unactivated alkenes was developed, providing 1,2,3-triazole containing bisheterocycles bearing all-carbon quaternary centers with yields of 25–90%. The protocol was extended to 1,3,4-oxadiazoles as well. The installed triazole was further exploited for late-stage functionalizations, and the mechanistic studies indicate
开发了钯催化的未活化烯烃的多米诺骨牌Heck /分子间直接杂芳基化序列,提供了带有1,2,3-三唑的双环杂环带有全碳四元中心的双环,收率为25–90%。该协议也扩展到了1,3,4-恶二唑。已安装的三唑被进一步用于后期功能化,并且机理研究表明C–H活化的参与。
