Three-Component Reaction for the Synthesis of Highly Functionalized Propargyl Ethers

Jérôme Waser, Guillaume Dominique Pisella, Alec Gagnebin

Multicomponent reactions provide efficient means to access molecular complexity. Herein, we report a copper-catalyzed three-component reaction of diazo compounds, alcohols and ethynyl benziodoxole (EBX) reagents for the synthesis of propargyl ethers. Exten ...

Copper-Catalyzed Oxyvinylation of Diazo Compounds

Jérôme Waser, Guillaume Dominique Pisella, Alec Gagnebin

A copper(I)-catalyzed vinylation of diazo compounds with vinylbenziodoxolone reagents (VBX) as partners is reported. The transformation tolerates diverse functionalities on both reagents delivering polyfunctionalized vinylated products. The strategy was su ...

Metal-Free Electrophilic Alkynylation of Sulfenate Anions with Ethynylbenziodoxolone Reagents

Jérôme Waser, Stefano Nicolai, Franck Le Vaillant, Stephanie Grace Elizabeth Amos, Alec Gagnebin

Alkynyl sulfoxides are important building blocks with a unique reactivity in organic chemistry, but only a few reliable methods have been reported to synthesize them. A novel route to access alkynyl sulfoxides is reported herein by using ethynyl benziodoxo ...

Synthesis of bicyclo[3.1.0]hexanes by (3+2) annulation of cyclopropenes with aminocyclopropanes

Jérôme Waser, Bastian Antoine Rodolphe Claude Muriel, Alec Gagnebin

We report the convergent synthesis of bicyclo[3.1.0]hexanes possessing an all-carbon quaternary center via a (3 + 2) annulation of cyclopropenes with cyclopropylanilines. Using an organic or an iridium photoredox catalyst and blue LED irradiation, good yie ...
