The Suero research group has developed new catalytic methods involving conceptually-novel radical carbenoids, carbyne equivalents, and metal-carbynoids and studied their behavior towards fine & feedstock chemicals as well as medically relevant agents.
The research of the Echavarren group centers on the development of new reactions based on the use of electrophilic complexes of Au(I), Pt(II), and other transition metals as catalysts and their applications in organic synthesis of complex, biologically active molecules.
Oxazolidinone chiral auxiliaries are often used for diastereoselective Michael additions, alkylations, aldol condensations, cyclopropanations, Diels-Alder, and other reactions. We operates 29 manufacturing facilities globally to supply your development and scale-up needs.
We are proud to offer a treasure-trove of gold precatalysts and silver salts, as well as an extensive portfolio of unsaturated building blocks to accelerate your research success in this exciting field.
Solvias MeOBIPHEP Ligands: State-of-the-art atropisomeric MeOBIPHEP ligands, also referred to as MeO-BIPHEP, originally developed by Roche, have an extraordinarily broad performance profile for many synthetic applications due to their modular ligand design.
Purchase our lipids and fatty acids standards suitable for your broad range of industrial applications specifically for food matrix testing, microbiology testing, analysis of functional foods or nutraceutical formulations, clinical and diagnostic testing, and biomarker discovery, both prognostic and diagnostic.
Echavarren and co-workers have also demonstrated the utility of Au-NHCs in the reactions of 1,6-enynes. They determined that the outcome of the cyclization of 1,6-enyne 1 was dependent on the ligand coordinated to the metal. When 2 was used in...
Transformative reagents for selective metalation, deprotonation and nucleophilic additions have allowed for unprecedented selective converstions to reactive intermediates within a molecule which contains sensative functionalities under mild reactions.
