Abstract

Abstract Image

A continuous flow inverse-electron-demand Kondrat’eva reaction has been developed that provides direct access to cycloalka[c]pyridines from unactivated oxazoles and cycloalkenes. Annulated pyridines obtained by this one-step process are valuable scaffolds for medicinal chemistry.
