Electroaffinity Labeling: A New Platform for Chemoproteomic-based Target Identification

Autor: Yu Kawamata, Keun Ah Ryu, Gary Hermann, Alexander Sandahl, Julien Vantourout, Aleksandra Olow, La-Tonya Adams, Eva Rivera-Chao, Lee Roberts, Rob Oslund, Olugbeminiyi Fadeyi, phil baran

Target identification is a critical pillar within the drug discovery process that involves deconvoluting the protein target of a pharmacologically active small molecule ligand. While photoaffinity labeling strategies have become the benchmark for tar

Copper‐Catalyzed Enantioselective Allylboration of Alkynes: Synthesis of Highly Versatile Multifunctional Building Blocks

Autor: Martín Fañanás-Mastral, Eva Rivera-Chao, Maider Mitxelena, Jesús A. Varela

Publikováno v: Angewandte Chemie. 131:18398-18402

The first copper-catalyzed enantioselective allylboration of alkynes is reported. The method employs a multitasking chiral NHC-Cu catalyst and provides access to densely functionalized molecules from simple starting materials with excellent levels of

Synthesis and Characterization of Bidentate (P^N)Gold(III) Fluoride Complexes: Reactivity Platforms for Reductive Elimination Studies

Autor: Alexandre Genoux, Michał Biedrzycki, Eva Rivera-Chao, Estíbaliz Merino, Anthony Linden, Cristina Nevado

Publikováno v: Angewandte Chemie (International ed. in English). 60(8)

A new family of cationic, bidentate (P^N)gold(III) fluoride complexes has been prepared and a detailed characterization of the gold‐fluoride bond has been carried out. Our results correlate with the observed reactivity of the fluoro ligand, which u

Copper-catalyzed protoboration of borylated dendralenes: a regio- and stereoselective access to functionalized 1,3-dienes

Autor: Eva Rivera-Chao, Martín Fañanás-Mastral, Andrea Chaves-Pouso

A copper-catalyzed protoboration of borylated dendralenes is reported. The method employs an NHC–Cu catalyst and provides access to 1,4-addition products with excellent levels of chemo-, regio- and stereoselectivity. The resulting diene bis(boronat
