Abstract

New Cinchona alkaloids-1,2,3-triazole derivatives library was prepared readily and efficiently using Huisgen 1,3-dipolar cycloaddition of 9-azido substituted Cinchona alkaloids and various terminal and disubstituted alkynes (click chemistry). Spectroscopic, X-Ray, and molecular modelling data show that these derivatives maintain the conformation of the parent alkaloids.
