Synthesis of Some Oxygen and Nitrogen Heterocycles from 6-Formyl-7-hydroxy-5-methoxy-2-methylchromone

6-Formyl-7-hydroxy-5-methoxy-2-methylbenzopyran-4-one (I) on condensation with hippuric acid/acetylglycine in the presence of Ac2O-NaOAc affords the oxazolin-5-one derivatives (IIa,b, respectively).These oxazolones undergo ring-opening by the action of
