title: Copper-catalyzed oxidative amination of benzoxazoles via C-H and C-N bond activation: a new strategy for using tertiary amines as nitrogen group sources.
abstract: An efficient and conceptually new method for oxidative amination of azoles with tertiary amines via copper-catalyzed C-H and C-N bond activation has been developed. This protocol can be performed in the absence of external base and only requires atmospheric oxygen as oxidant. The catalyst system is very simple and efficient, which opens a new way for using tertiary amines as nitrogen group sources for C-N bond formation reactions.
