A sequential copper-catalyzed, one-pot, click reaction–intramolecular direct arylation, which involves two mechanistically distinct reactions (atom-economical clickreaction and direct arylation of 1,2,3-triazole), to generate [6,6]-, [6,7]-, [6,8]-, and [6,9]ring-fusedtriazoles is reported. Furthermore, a unique divergence of reactivity between the fusedtriazoles prepared from 2-bromobenzyl azide

A convenient approach to the synthesis of novel triazole-N-glycoside derivatives was developed via CuSCN-catalyzed click reaction and Ullmann-type coupling reaction for the first time. The SGLT2 inhibitory activities of these synthetic N-glycosides were evaluated, and some compounds showed moderate SGLT2 inhibition activities at 100 nM. The results could benefit the discovery of new SGLT2 inhibitors for the treatment of diabetes. (C) 2015 Elsevier Ltd. All rights reserved.
