Expedient synthesis of imino-C-nucleoside fleximers featuring a one-pot procedure to prepare aryl triazoles†
Abstract
Nucleoside analogues such as the antiviral agents galidesivir and ribavirin are of synthetic interest. This work reports a “one-pot” preparation of similar fleximers using a bifunctional copper catalyst that generates the aryl azide in situ, which is captured by a terminal alkyne to effect triazole formation.
