A novel palladium(II)-catalyzedintramolecular [2 + 2 + 2] annulation of indolyl 1,3-diynes is described in this contribution. A variety of azepino-fused carbazoles are obtained in moderate to excellent yields. The key to the success of this transformation is the use of a carboxylic acid as an additive. This protocol features broad functional group tolerances, easy handling in air, and 100% atom economy

cascade gold(I)-catalyzed hydroarylation of alkynylindoles and subsequent Diels–Alder cycloaddition with electron-deficient alkynes and alkenes is described. A variety of azepino-fused hydrocarbazoles and carbazoles were obtained in moderate to excellent yields. Key features of this methodology are low catalyst loadings, high regioselectivity, broad functional group tolerances, access to important
在此,描述了一种新型级联金( I )催化的炔吲哚加氢芳基化反应以及随后与缺电子炔烃和烯烃的狄尔斯-阿尔德环加成反应。以中等至优异的产率获得了多种氮杂环稠合氢咔唑和咔唑。该方法的主要特点是催化剂负载量低、区域选择性高、官能团耐受性广、可获得重要的杂环以及 100% 原子经济性。
