NBS-mediated dinitrogen extrusion of diazoacetamides under catalyst-free conditions: practical access to 3-bromooxindole derivatives†
Abstract
A synthetically useful transformation arises from NBS-mediated dinitrogen extrusion of N-aryl diazoacetamides under catalyst-free conditions, which gives 3-bromooxindoles in high to excellent yields with high selectivity via a non-carbene process.
