This review delves into recent advances and significant breakthroughs in the field of the
catalytic Friedel–Crafts alkylation of targeted arenes or heteroarenes. Though a few earlier …

Indole, widely recognized as a versatile category of heterocyclic frameworks that contain
nitrogen is extensively employed in the synthesis of various organic compounds due to their …

A benign approach to valuable 3-aryl-indolin-2-ones was developed based on palladium
(II)/Lewis acid-cocatalyzed cyclocarbonylation of readily available (2-aminoaryl)(aryl) …

We developed a modular synthesis for 3, 3-disubstituted oxindoles, utilising readily
accessible nitrones and acrylic acids. This approach facilitates the preparation of a diverse …

Presented herein is a novel synthesis of unsymmetrical 3, 3-diaryl oxindoles and 4, 4-diaryl
isoquinolinediones through the cascade reactions of 2-phenoxy-1H-benzo [d] imidazoles …

Nitroarenes are known for their stability, low toxicity, easy availability, and cost-effectiveness,
making them one of the most fundamental chemical feedstocks. The direct utilization of …

We have developed a highly efficient base-and additive-free chemoselective CuO-catalyzed
strategy for the O-arylation of 2-oxindoles to synthesize 2-phenoxy-3 H-indole and 2 …

A simple and efficient method for structurally diverse symmetrical and unsymmetrical 3, 3′-
and 2, 3′-bisindolylmethanes has been developed through a one-pot sequential reaction …

Herein, we introduce a mild and efficient method for synthesizing aniline biaryls and
unsymmetrical phenol biaryls through iodine-catalyzed coupling of quinone imine ketals …

In this study, we have disclosed N-alkylation and C-alkylation reactions of 2-oxindoles with
secondary alcohols. Interestingly, these chemoselective reactions are tunable by changing …
