    of the most popular one-pot glycosylation strategies is orthogonal one-pot synthesis, which was mainly based on thioglycosides. Despite its successful application, shortcomings of thioglycosides including aglycon transfers, interference of departing species and unpleasant odor restrict its application scope. Herein, we report a new and efficient orthogonal one-pot synthesis of oligosaccahrides based
    正交一锅合成是最流行的一锅糖基化策略之一,其主要基于硫代糖苷。尽管已成功应用,但是硫糖苷的缺点包括糖苷配基转移,离去物种的干扰和难闻的气味限制了其应用范围。在本文中,我们报告了一种基于糖基邻炔基苯甲酸酯的新型高效正交一锅合成寡糖的方法,解决了基于硫代糖苷的正交一锅合成的问题。通过这种方法已经有效地合成了十几种寡糖。

Condensation of 6 with 7 gave the disaccharide donor 8, and subsequent condensation of 8 with 4-methoxyphenyl 2.3.4-tri-O-benzoyl-beta-D-galactopyranosyl-(1-->6)-2-O-acetyl-3,4-di-O-benzoyl-beta-D-galactopyranoside (9) followed by selective deacetylation afforded the tetrasaccharide acceptor 11. Coupling of I I with 12 gave the pentasaccharide 13, its deallylation followed by coupling with 12. and debenzoylation Rave the hexasaccharide 16 with beta-(1-->6)-linked galactopyranose backbone and 2- and 3"-linked alpha-L-arabinofuranose side chains. The octasaccharide 27 was similarly synthesized, while the twentyoside 42 was synthesized with tetrasaccharides 33 or 24 as the donors and 23, 36, 38, and 40 as the acceptors by consecutive couplings followed by deacylation.
