A Catalyst-free Synthesis of Pyrazolopyridines Derived from Alicyclic Mono-ketones

摘要

Inactive alicyclicmono-ketones (cyclohexanone and cyclopentanone) were firstly used as reactants to prepare pyrazolopyridine derivatives in good yield through their catalyst-free reaction with 5-aminopyrazole and aromatic aldehyde in ionic liquid.
