Conspectus The activation of molecular hydrogen by main-group element catalysts is an
extremely important approach to metal-free hydrogenations. These so-called frustrated …

The derivatives of indoles are very useful intermediates in pharmaceuticals and organic
synthesis. The efficient synthesis of the indole blocks and related functionalizations …

[3, 4]-Fused oxindoles are the core structures of the naturally occurring oxindole alkaloids,
and the fused tricyclic structures have distinguished themselves with unique biological …

The rapid assembly of complex scaffolds in a single step from simple precursors identifies as
an ideal reaction in terms of efficiency and sustainability. Indeed, the direct single-step …

The H2O-promoted controllable synthesis of diverse nitrogen heterocycles from readily
available feedstocks was developed by a hydride transfer strategy. A variety of 3-carboxyl …

An unprecedented organocatalytic cascade aldimine condensation/[1, 6]-hydride
transfer/Mannich-type cyclization of indole-2-carbaldehydes with o-aminoanilines was …

An unprecedented redox-neutral annulation reaction of tertiary anilines with electron-
deficient alkynes was developed that proceeds through a cascade Friedel–Crafts …

The dearomative [5+ 1] annulation of 2-methylindoles with new five-membered synthons O-
alkyl ortho-oxybenzaldehydes was developed unprecedentedly through cascade [1, 5] …

In this paper, a series of novel carbazolequinones were efficiently obtained by a B (C6F5) 3-
catalyzed [4+ 2] cyclization reaction. This protocol not only had a simple operation, broad …

Hydride shuttle catalysis has emerged as a powerful synthetic platform, enabling the
selective formation of C–C bonds to yield sp3-rich structures. By virtue of the compelling …
