Transition metal‐catalyzed carbene transfer reactions have a century‐old history in organic
chemistry and are a primary method for the synthesis of cyclopropanes. Much of the work in …

The stereoselective cyclopropanation of olefins with “boron ylide” is disclosed for the first
time, providing a modular strategy for the synthesis of stereospecific diboryl‐functionalized …

A radical mechanism enables simple and robust access to nonstabilized, alkyl iron carbenes
for novel (2+ 1) cycloadditions. This Fe-catalyzed strategy employs simple, aliphatic …

We report a novel cyano migration-mediated radical-polar crossover process, whereby both
the sulfonylcyanation of aliphatic alkenes and the formation of cyclopropanes are …

The ability to tame high-energy intermediates is critical for synthetic chemistry, enabling the
construction of complex molecules and propelling advances in the field of synthesis. Along …

An expedient approach to the synthesis of 4-azaspiro [2.3] hexane derivatives is described.
The synthetic scheme consists of Tebbe olefination of N-Boc-protected 2-azetidinone …

Oxetanes, 4-membered oxygen-containing heterocycles, were identified to have
pharmaceutical applications after the discovery of the chemotherapeutic drug taxol …

Cyclopropanes are valuable motifs in organic synthesis, widely featured in pharmaceuticals
and functional materials. Herein, we report an efficient electrochemical methodology for the …

Efficient and straightforward synthesis of complex molecules has always been a long-
standing aspiration and challenge in organic chemistry. To meet the ever-growing demand …

To expand the substrate scope of the recently named “Radical Cation Induced Addition
(RCIA)”, allowing functionalization of inactivated alkenes, the concept of “metal complex …
