Copper-catalysed dehydrogenative α-C(sp3)–H amination of tetrahydroquinolines with O-benzoyl hydroxylamines†
Abstract
A copper-catalysed dehydrogenative α-C(sp3)–H amination of tetrahydroquinolines with O-benzoyl hydroxylamines has been demonstrated for the first time, which proceeds with the merits of operational simplicity, good functional tolerance, mild conditions, the use of O2 as the oxidant and no need for the installation of directing groups.
