organic molecules are on demand. Here we present two Pd-catalyzed multicomponent reactions that provide functionalized oxazolidinones from propargylamines, aryl halides and CO2 as starting materials. These transformations, devoid of high CO2 pressures, represent a streamlined stereocontrolledsynthesis of previously inaccessible versions of these useful heterocycles in an atom-economic manner, as up to
The present invention provides modified metal surfaces, methods of preparing the same, and intermediates thereto. These materials are useful in a variety of applications including biomaterials.
