The synthesis of previously unreported 2-arylimino-2H-pyrancarboxaldehydes is achieved by the treatment of Vilsmeier reagent with N-arylacetoacetamides. 2-N-Alkyl and the parent 2-imino-2H-pyrancarboxaldehyde derivatives are synthesized from the corresponding acetoacetamide derivatives. A possible m
