Conspectus Seven-membered rings fused with an indole are termed cyclohepta [b] indoles.
Compounds exhibiting this structure motif display a broad spectrum of biological activities …

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

Aminobenzaldehydes react with indoles in an unprecedented cascade reaction. This acid-
catalyzed redox-neutral annulation proceeds via a condensation/1, 5-hydride shift/ring …

A tandem double Friedel Crafts reaction of indoles with 2-formylbiphenyls, leading to 9-(3-
indolyl) fluorene derivatives with up to 96% ee was reported. Several solvents, namely …

In this review, we discuss Friedel-Crafts-type aromatic amidation and acylation reactions, not
exhaustively, but mainly based on our research results. The electrophilic species involved …

Indoles display a diverse pattern of reactivity upon reaction with different classes of
aminobenzaldehydes. Whereas the acid-promoted reaction with secondary …

A robust metal-free and environmentally friendly approach to cyclohepta [b] indole and furo
[3, 4-b] carbazole frameworks via a three-component reaction from indoles, tertiary …

The gold‐catalysed double functionalisation of indoles is presented. Enynones are used to
annulate indoles via a double sodium tetrachloroaurate‐catalysed process involving a …

Cascade transformations forming multiple bonds and one‐pot procedures provide rapid
access to natural‐product‐like scaffolds from simple precursors. These atom‐economic …

A strategy for synthesizing highly functionalized cyclohepta [b] indoles through a concise (4+
3) cycloaddition–cyclization–elimination sequence is described. The cycloaddition features …
