Abstract:
New spiroindeno[1,2-b]quinoxaline and spiroindeno[1,2-b]pyrazine derivatives containing pyrano group were synthesized via one-pot three component reaction of indeno[1,2-b]quinoxaline and indeno[1,2-b]pyrazine, malono derivatives with various α-methylenecarbonyl compounds (β-diketones, pyrazolones) in ethanol catalyzed by piperidine.
