Abstract: Abstract The present study describes L-hydroxy proline catalyzed unpredicted formation of 4,5-dihydro-1H-pyrazolo[3,4-b]pyridines instead of expected 4,7-dihydro-1H-pyrazolo[3,4-b]pyridines in aqueous ethanol at ambient temperature through one-pot three-component reaction. Furthermore, this protocol was evaluated using green chemistry metrics… read more here.
