Pyrano[4,3-d]pyrimidinium salts 5. Synthesis of 7-aryl-1,3-dimethyl-2,4- dioxo-1H,3H-pyrano[4,3-d]pyrimidinium salts and their reactions with nucleophiles

7-Arylpyrano[4,3-d]pyrimidinium salts were synthesized starting from 1,3,6-trimethyluracil. In the reactions with N-nucleophiles, these salts were found to undergo recyclization of the pyrylium ring, whereas the addition of C- and O-nucleophiles occurs at
