N-amidation by copper-mediated cross-coupling of organostannanes or boronic acids with O-acetyl hydroxamic acids

摘要

A general nonoxidative N-amidation of organostannanes and boronic acids has been developed. Under nonbasic conditions a wide variety of aryl, alkenyl, and heteroaryl organostannanes and boronic acids couple efficiently with O-acetyl hydroxamic acids in the presence of Cu(I) sources.
