摘要
We have developed an efficient method for the synthesis of functionalized C-glycosyl 1,2,3-triazoles through a Cu(1)-promoted azide-alkyne 1,3-dipolar cycloaddition between a TMS-protected C-alkynyl-glycoside and organic azides. The reaction was accelerated by ultrasound irradiation and the addition of a base was not necessary to obtain the 1,2,3-triazole product. Moreover, further manipulation of the products led to chiral molecules with a C-glycoside linkage. (C) 2012 Elsevier Ltd. All rights reserved.
