Synthesis and reactivity of methyl 3-acyl-6-amino-4-aryl-5-cyano-4h-pyran- 2-carboxylates

By treating arylidenemalononitriles with methyl 2,4-dioxobutanoates, derivatives of 4H-pyrans - methyl 3-acyl-6-amino-4-aryl-5-cyano-4H-pyran-2- carboxylates - are obtained, which are novel, promising structural components for the synthesis of carbo- and
