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.

Derivatives of (1,2,3-triazol-4-yl) benzenamines are described as potent and ATP-competitive inhibitors of vascular endothelial growth factor receptors I and II (VEGFR-1/2). A number of compounds exhibited VEGFR-2 and VEGFR-1 inhibitory activity comparable to that of Vatalanib (TM) in both HTRF enzymatic and cellular assays. (C) 2009 Elsevier Ltd. All rights reserved.
