1. INTRODUCTION Bicyclic oxygen heterocycles resulting from fusion of benzene ring with
5, 6-positions of either 2H-or 4H-pyran ring system are designated as 2H-chromene (2H-1 …

Spirans contain at least two rings, which share one carbon atom called the spirocarbon
atom. 1 Synthetic and natural spirocarbocycles attract the attention of organic chemists due …

Intermolecular annulation reactions of 1-aryl-2-naphthols with internal alkynes proceed
efficiently in the presence of a Ru catalyst and a Cu oxidant to generate spirocyclic …

Metal-catalyzed olefin metathesis has become one of the most widely used organometallic
transformations for carbon-carbon formation in organic synthesis. For this reason, the Royal …

Since its discovery by Christoph Hartmann and Victor Meyer in 1893, 2‐iodoxybenzoic acid
(IBX) has emerged as a rather ubiquitous oxidant for organic synthesis. The past decade …

Sulfones display a diverse range of behavior and possess unique features that make them
valuable for numerous types of synthetic applications. As a result of their utility and …

The design and synthesis of spirocycles is a challenging task because it involves the
creation of a quaternary center, which itself is considered to be one of the most difficult tasks …

The Pauson-Khand reaction has in the past 50 years become one of the most common
cycloaddition reactions in chemistry. Coupling two unsaturated bonds with carbon …

In this account we disclose a variety of simple strategies demonstrated in our laboratory in
the last two decades for the assembly of diverse and intricate molecular frameworks …

We report non‐decarbonylative Mizoroki–Heck reactions of amide derivatives. The
transformation relies on the use of nickel catalysis and proceeds using sterically hindered tri …
