Stereoselective fucosylation of Boc-Ser/Thr/Tyr-OMe 2â4 and several saccharide alcohols 5â7 by coupling with 2-pyridyl tri-O-benzyl-1-thio-β-L-fucosyl donor 1b under iodomethane activation procedure results in the formation of α-linked fucosylated amino acid methyl ester building blocks 8â10 and α-linked fucosyl saccharides 11â13, respectively.
在碘甲烷活化程序下,Boc-Ser/Thr/Tyr-OMe 2至4与2-吡啶基三-O-苄基-1-硫-β-L-岩藻糖供体1b偶联,以及几种糖醇5至7与该供体偶联,分别形成了α-连接的岩藻糖基化氨基酸甲酯结构单元8至10和α-连接的岩藻糖基糖11至13。
