method has been developed to construct highly functionalized N‐bridgeheadazepineskeletons, which are of great importance in biological and pharmaceutical industry. The reaction proceeds through a rhodium(II) azavinyl carbene intermediate, which initiated the intramolecular CH functionalization with pyrrolyl and indolyl rings. A variety of azepine derivatives were obtained in moderate to good yields under

A Cu(I)-catalyzed [3 + 2] intramolecular cycloaddition reaction of N-indole-tethered cyclopropenes is presented in this paper. This reaction starts from the formation of π-allyl cationic intermediate or its resonance-stabilized metal carbenoid intermediate upon activation of cyclopropene with Cu(I) catalyst and a Friedel–Crafts-type cyclization to give functionalized hydrogenated diazabenzo[a]cyclopenta[cd]azulenes
本文提出了Cu(I)催化的N吲哚系环丙烯的[3 + 2]分子内环加成反应。该反应始于在用Cu(I)催化剂活化环丙烯并进行Friedel-Crafts型环化反应以形成官能化的氢化二氮杂苯并[ a ]环戊[ cd ]之后,形成π-烯丙基阳离子中间体或其共振稳定的金属类化合物中间体。天青石的产量高到极好,dr值中等到良好。可以实现该环加成反应的不对称变体,从而得到具有中等ee值的所需产物。

Cascade fluorofunctionalisation of 2,3-unsubstituted indoles featuring the formation of C–C, C–F and C–O bonds via electrophilic fluorination using N-fluorobenzenesulfonimide is described. The use of an O-nucleophile tethered to the nitrogen of indoles enables the synthesis of polycyclic fluorinated indoline derivatives from simple precursors in 40–63% yields.
A highly efficient catalytic dearomatization of indoles via visible-light photocatalysis is presented. The common indole tethered alcohol at the N1 or C2 position reacts in a cascade fashion, providing facile access to diverse indolone scaffolds.
