Synthesis of 1,2,3-Triazole Derivatives by Cyclocondensation of Alkyl Azides with Active Methylene Ketones in the System K2CO3/DMSO
Abstract: The reaction of β-keto esters or acetylacetone with alkyl azides in the system K2CO3/DMSO proved to be a convenient method of synthesis of tri- and disubstituted 1-alkyl-1H-1,2,3-triazoles.
