Kinetic studies on cyclization of 2-(2'-pyridyl)-cyclohexanone oxime hydrogensulfate and its derivatives bearing a substituent on pyridine ring to the corresponding 2,3-tetramethylenepyrazolopyridines were carried out in buffered solutions or in presence of NaHCO3.A two-stage mechanism of the cyclization was proposed.

The synthesis of oxime hydrogensulfates of 1-(2'-pyridyl)-2-propanone, 2-(2'-pyridyl)cyclopentanone and 2-(2'-pyridyl)cyclohexanone and attempts at their cyclization to corresponding pyrazolopyridines are presented.Good yields of the cyclization products are obtained from oxime hydrogensulfate of 2-(2'-pyridyl)cyclohexanone and its derivatives bearing a substituent on a pyridine ring.
