Transition metal-catalyzed cyclization reactions of unsaturated substrates have become one
of the most important and useful methodologies for the preparation of heterocycles. To this …

Indoles are important structural motifs that are commonly found in a diverse array of natural
products, pharmaceuticals, and other functional molecules. Consequently, the development …

The synthesis of isoquinolines by site‐selective C H activation of O‐acyl oximes with a Cp*
CoIII catalyst is described. In the presence of this catalyst, the C H activation of various …

In this paper, a highly efficient and regioselective synthesis of pyrazolone fused
benzodiazepine derivatives via the reaction of 1-phenylpyrazolidinones with propargyl …

An efficient, scalable, atom-economical, regio-selective air stable Cp* Co (III) catalyzed C–H
and C–O coupling via a C–H activation/oxygen atom transfer reaction of quinoline N-oxide …

A mild Co (III)-catalyzed oxidative annulation of N-arylureas and internal alkynes has been
developed. The use of less electrophilic ureas other than acetamides as directing groups is …

Abstract The direct C H annulation of anilines or related compounds with internal alkynes
provides straightforward access to 2, 3‐disubstituted indole products. However, this …

The ability to establish switchable site-selectivity through catalyst control in the direct
functionalization of molecules that contain distinct C–H bonds remains a demanding …

A highly efficient iridium-catalyzed cascade annulation of pyrazolones and sulfoxonium
ylides to access various pyrazolo [1, 2-α] cinnoline derivatives has been achieved. This …

A facile and efficient approach for the direct thiocyanation of pyrazolin-5-ones via a radical
mechanism has been established for the first time. A series of 4-thiocyanated 5-hydroxy-1H …
