Abstract: Reaction of 4-hydroxy-6-methyl-2-pyrone (1a) as well as 4-hydroxy-6-methyl-2(1H)-pyridones (1b-d) with arylmethylene malononitriles or arylmethylene methyl cyanoacetates (2a-h) leads to the formation of the very stable 5,6-fused bicyclic 2-amino-4Hpyran derivatives 3a-3af.
Keywords: pyrano[4; 3-b]pyran; pyrano[3; 2-c]pyridine; arylmethylene malononitrile; arylmethylene cyanoacetate; Michael addition
