Preparation and Thermolysis of cis- and trans-1-Hydroxy-2-(2-pyridyl)cyclopentanes and cis- and trans-1-Hydroxy-2-(2-pyrazyl)cyclopentanes
The syntheses of cis- and trans-1-hydroxy-2-(2-pyridyl)cyclopentanes as well as cis- and trans-1-hydroxy-2-(2-pyrazyl)cyclopentanes have been carried out, and their stereochemical assignments were done by using IR and NMR data.The thermolyses of these pyrazylethanols and pyridylethanols have been studied in diglyme solutions at 170 deg C.While the pyrazylethanols mainly undergo dehydration, the pyridylethanols thermolyze via a much more complex reaction process.

OXIME HYDROGENSULFATES OF α-(2-PYRIDYL)ALKANONES AND THEIR CYCLIZATION TO PYRAZOLOPYRIDINES
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.
