[4,4′-Bi-1H-pyrazolo[3,4-b]pyridines] from 1,6-Diaryl-1,3,4,6-hexanetetronesReaction of 1,6-diaryl-1,3,4,6-hexanetetrones 1a-c (Ar = phenyl, p-tolyl or 2-thienyl) with 3-amino-1-phenyl-5-pyrazolone (2) in the presence of piperidine leads to 6,6′-diaryl-2,2′-diphenyl[4,4′-bi-1H-pyrazolo[3,4-b]pyridine]-3,3′(2H,2′H)diones 3a-c, which are transformed into the acetates 4a-c.
