Acylation of cyclic nitronates with acyl bromides produces 3-bromomethyl-substituted 5,6-dihydro-2H-1,2-oxazines via an unusual multi-stage process involving deoxygenation of N-oxide and the formation of Br2. Low-temperature in situ ATR FT-IR monitoring and DFT calculations revealed α-halo-substituted N,N-bis(oxy)amines as key intermediates of the process. The developed method was successfully exploited in the stereoselective synthesis of pharmaceutically relevant molecules.
