- N - Oxide (Diazine -)N-The position selective Oxides-C alkylation of H) relates to a method alkylation. To the present invention, a plurality of diazine compounds can be alkylated by selectively introducing an alkyl group to a diazine compound known as a core unit structure in a medicine, and synthesis of a plurality of diazine compounds (varenicline) paenibacillin A, which is a natural product, can be synthesized.

The condensation of the two oligoheterocyclic aldehydes 8 and 16 with the bis-hydrazine 17 gives the bis-hydrazones 1 and 2. These molecular strands are shown to adopt helical conformations of 1.5 and 2.5 turns, respectively. The helical shape of 1 has be
