Abstract


The review summarizes and systematizes the literature data on the use of 5(4)-aminopyrazoles in the synthesis of pyrazolo[3,4-b]- and pyrazolo[4,3-b]pyridines. The synthetic methods are classified on the basis of how well studied the pyrazolopyridine fragment is, i.e from more to less studied. The bibliography of the review includes 91 references published over the last two decades.
