A series of 3,7a-diazacyclohepta[jk]fluorene derivatives were synthesized via a gold(I)-catalyzed 6-exo-dig hydroamination/7-endo-dig cycloisomerization domino method. The method exhibits a broad substrate scope, and a plausible mechanism has been proposed. The efficacy of this strategy is further validated by the successful derivatization of 3,7a-diazacyclohepta[jk]fluorene.

金（I）催化的 6-exo-dig 氢胺化/7-endo-dig 环异构化 3,7a-二氮杂环庚[jk]芴衍生物的 Domino 方法


通过金 （I） 催化的 6-exo-dig 氢胺化/7-endo-dig 环异构化多米诺骨牌法合成了一系列3,7 α-二氮杂环庚 [jk] 芴衍生物。该方法表现出广泛的衬底范围，并且已经提出了一种合理的机制。3,7a-二氮杂环庚[jk]芴的成功衍生化进一步验证了该策略的有效性。
