Abstract
The highly reactive 1 : 1 intermediate generated in the reaction between dialkyl acetylenedicarboxylate (=but-2-ynedioic acid dialkyl ester) 4 and triphenylphosphine was trapped by 2-amino-4-oxo-4H-1-benzopyran-3-carboxaldehydes 5 to yield highly functionalized dialkyl-1,5-dihydro-5-oxo-1-phenyl-2H-[1]benzopyrano[2,3-b]pyridine-2,3-dicarboxylates in high yield.
