Abstract
Formylation of 4-hydroxy-6-methyl-2(1H)-pyridones and subsequent cycli zation with a Wittig reagent or with CH-acidic esters gave a series of title compounds. The same starting pyridones reacted with methyl 3-am ino-2-butenoate directly to the corresponding 4,7-dimethylpyrano[3,2-c ]pyridines.
