ABSTRACT
A facile method for the synthesis of bis-pyrazolo[3,4-b4',3'-e]pyridines from easily available aromatic aldehydes and pyrazol-5-amines was developed via electrochemistry. The reaction proceeded smoothly under metal and external chemical oxidant-free conditions, giving a variety of bis-pyrazolo[3,4-b4',3'-e]pyridines in moderate yields.
