Several approaches to cyanide ion-catalyzed synthesis of 4-aroyl-1-phenyl-1h-pyrazolo[3,4-d]pyrimidines

- 4-Aroyl-1-phenyl-1H-pyrazolo[3,4-d]pyrimidines (5) were formed in low yields by reaction of 4-chloro-1-phenyl-1H-pyrazolo[3,4-d]pyrimidine (4) with arenecarbaldehydes (3) in the presence of potassium cyanide. Similar reaction of 4-tosyl-1-phenyl-1H-pyra

Catalytic action of azolium salts. IV. Preparations of 4-aroylquinazolines and 4-aroyl-1H-pyrazolo[3,4-d]pyrimidines by catalytic action of 1,3-dimethylimidazolium iodide

The ability of 1,3-dimethylimidazolium iodide (1) to catalyze the aroylation of the chloroheteroarenes 4-8 with arenecarbaldehydes 3 as sources of the aroyl groups was examined in order to develop a preparative method of aroylheteroarenes. In the presence
