Bis-triphenylphosphano-copper(I)-butyrate (C3H7COOCu(PPh3)(2)) was applied for the synthesis of O-peracylated 1-glycopyranosyl-4-substituted-1,2,3-triazoles from the corresponding glycosyl azides and alkynes. This catalyst proved superior to the CuSO4/L-ascorbic acid system even with sterically hindered and less reactive glycosyl azides. (C) 2012 Elsevier Ltd. All rights reserved.
