Transition-metal-catalyzed cross-coupling reactions have been well-established as
indispensable tools in modern organic synthesis. One of the major research goals in cross …

This article reviews synthetic transformations involving cleavage of a carbon–carbon bond of
a four-membered ring, with a particular focus on the examples reported during the period …

In 1994, Ye and McKervey published a paper in Chemical Reviews entitled “Organic
Synthesis with α-Diazocarbonyl Compounds”. 1 Our intention then was to draw attention to …

Ketones and aldehydes play central roles in organic synthesis. There are numerous broadly
used reactions that are related to the carbonyl reactivity, such as Grignard reactions, Wittig …

N-Tosylhydrazones have recently emerged as useful synthons in a variety of transition-metal-
catalyzed and transition-metal-free reactions, which affords novel methodologies for the …

The development of new strategies and chemical reactions continues to be a major focus of
research efforts in the modern synthetic organic community. 1 Of the various types of …

Conventional organic synthesis has been mainly based upon the reactivities of π-bonds and
polar σ-bonds. Carbon–carbon single bonds are nonpolar and generally far less reactive …

A regioselective synthesis of β-and γ-fluorinated ketones via silver-catalyzed ring opening is
described. A variety of β-and γ-fluorinated ketones are efficiently prepared, respectively …

We describe a synergistic utilization of cerium photocatalysis and photoinduced electron
transfer catalysis that enables an atom-and step-economical ring expansion of readily …

A remaining challenge in the synthetic chemistry field is formation of all-carbon quaternary
centers, a feature found in many natural products, particularly in spirocycle systems. 1 …
