One-pot and convenient conversion of 5-azidopyrazole-4-carboxaldehyde to pyrazolo[3,4-b]pyridines
A one-pot and convenient synthesis of multisubstituted pyrazolo[3, 4-b]pyridines in moderate to high yields has been achieved by a two-step reaction: diazo-transfer of 5-azido-1-phenylpyrazole-4-carboxaldehydes to ketones in ethanolic KOH to give 5-amino-
