Abstract
A number of derivatives of 7-azaisatin with various substituents in the pyridine and pyrrole rings were synthesized by oxidation of the corresponding 7-azaindoles with chromic acid in acetic acid. 4-Azaindole is not oxidized to 4-azaisatin under these conditions. The β-thiosemicarbazones of the 7-azaisatin derivatives were obtained.
