Easy does it! The chemoselective oxidative α‐C(sp3)H alkylation/cyclization reaction of N‐benzyl carbamates using simple mono‐, di‐, and trisubstituted olefins provides functionalized N‐heterocycles such as oxazinones (see picture). A TEMPO oxoammonium salt serves as the oxidant, making it possible to carry out the reaction at low temperatures. Neither a metal catalyst nor preactivation in the α‐position

An efficient oxidative C–H alkynylation of N-carbamoyl tetrahydroisoquinolines mediated by a TEMPO oxoammonium salt has been established. A variety of electronically varied N-carbamoyl tetrahydroisoquinolines reacted with a range of alkynyl potassium trifluoroborates smoothly under mild metal-free conditions. Dihydroisoquinolines were also suitable components for the reaction. The synthetic applicability
