Synthesis and reactivity of 1-aryl-9h-thieno[3,4-b]chromon-9-ones

Methods were developed for the synthesis of 1-aryl-9H-thieno[3,4-b]chromon- 9-ones based on the reaction of bromo and dibromo derivatives of 2-methyl-4H-chromon-4-one with thioacetamide in DMF. The thienochromones were modified and their fluorescence prop

Phenylhydrazine as well as thiourea, like sodium acetate, brings about substitution of bromine in the title bromomethylpyranone 2. The pyranone 2 gives the pyrano fused oxazine 9 with hydroxylamine, pyridiazines 10 and 11, respectively with hydrazine and
