Article abstract of DOI:10.1002/hlca.19830660845

The nucleophilic attack of substituted anilines at position 6 of methyl coumalate (1) opens the α-pyrone ring to form 4-arylamino-3-(methoxycarbonyl)butadien-1-carboxylic acid 2 (Scheme 1).The latter are easily decarboxylated at room temperature in polar
