The [2+ 2+ 2] cycloaddition is an elegant, atom-efficient and group tolerant process for the
synthesis of carbo-and heterocycles, mostly aromatic, involving the formation of several C–C …

First-row transition-metal-mediated reactions constitute an important and growing area of
research due to the low cost, low toxicity, and exceptional synthetic versatility of these …

Reported herein is the novel gold‐catalyzed intermolecular [2+ 2+ 2] cycloaddition of

In recent years, many methods for the facile synthesis of pyridines and their derivatives have
been developed. The [2+ 2+ 2] cycloaddition reaction of alkynes and nitriles catalyzed by …

A Co‐catalyzed enantioselective desymmetric [2+ 2+ 2] cycloaddition for synthesis of
pyridines with all‐carbon quaternary carbon centers has been developed. The regio‐and …

Abstract The transition‐metal‐catalyzed [2+ 2+ 2] cycloaddition of nitriles and alkynes is an
established synthetic approach to pyridines; however, these cycloadditions often rely on the …

The synthesis of pyridines through direct intermolecular cycloaddition of alkynes and nitriles
is a contemporary challenge in organic synthesis. A Brønsted acid mediated formal [2+ 2+ 2] …

Cobalt cyclopentadienyl complexes incorporating a fumarate and a CO ligand (see picture)
