摘要：

A new synthetic strategy to obtain new linked 1,5-disubstituted tetrazole-1,2,3-triazoles via the Ugi-azide reaction followed by a copper-catalyzed alkyne-azide reaction (CuAAC) was developed. This strategy used solvent-free conditions for the Ugi-azide reaction. This two-step strategy affords the products in moderate to good yields. To the best of our knowledge, this is the first report using the CuAAC reaction as a post-condensation process in an Ugi-azide reaction and therefore, the first describing the synthesis of 1,5-disubstituted tetrazole (1,5-DS-T) linked to the 1,2,3-triazole moiety, which are molecules that may have potential applications in medicinal chemistry.
