Evaluation of bis-triphenylphosphano-copper(I)-butyrate (C3H7COOCu(PPh3)2) as catalyst for the synthesis of 1-glycopyranosyl-4-substituted-1,2,3-triazoles.
Bis-triphenylphosphano-copper(I)-butyrate (C(3)H(7)COOCu(PPh(3))(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 CuSO(4)/L-ascorbic acid system even with sterically hindered and less reactive glycosyl azides.
