N-Substituted 2-aminochromones and their benzo-fused derivatives were obtained in high yields by a new one-pot synthesis, starting from the appropriate acetamides, salicylic acid or its benzo-fused derivatives, and phosphoryl chloride. By the same reaction, from suitable dihydroxybenzenedicarboxylic acids, some compounds of two new structural classes, 2,7-diaminobenzo[1,2-b:4,5-b']dipyran-4,9-diones and 2,8-diamino-4H,6H-benzo[1,2-b:5,4-b']dipyran-4,6-diones, were synthesized.
