Expedient Microwave-Assisted Synthesis of Novel 6-Substituted 5-Alkoxy(benzyloxy)-3,6-dihydro-2H-1,3,4-oxadiazin-2-ones
摘要:
Novel 6-substituted 5-alkoxy(benzyloxy)-3,6-dihydro-2H-1,3,4-oxadiazin-2-ones have been prepared in good yields and very short reaction times by intramolecular cyclization of alpha-hydroxyhydrazonates in the presence of sodium ethoxide under microwave irradiation.

A series of previously unreported α‐hydroxy hydrazonates were synthesized and tested for their antimalarial properties. Structure optimization of the antiplasmodially active α‐hydroxy hydrazonate III furnished derivatives with strong in‐vitro antimalarial activity against 3D7 strains of Plasmodium falciparum with IC50 values lower than 2.0 µM.
