Abstract
2-Formyl-3-hydroxypyridine and its 6-methyl derivative have been condensed with ethoxycarbonylmethyl-enetriphenylphosphorane and alkyl derivatives to afford 5-azacoumarins substituted in the second case by an alkyl group at 3-position by two different ways according to the used phosphorane.
