In(OTf)3 efficiently activated N-phenyltrifluoroacetimidate and In(OTf)3 in combination with various halogenated reagents or PhIO promoted glycosylation using thioglycoside in good yields. The combination with iodine interhalogens (e.g., ICl or IBr) effectively promoted α-sialylation.
                                    In(OTf)3 高效激活了 N-苯基三
氟乙
酰亚胺,且 In(OTf)3 与各种卤素试剂或 PhIO 结合,促进了以
硫糖苷为底物的糖苷化反应,产率良好。与
碘卤素(如 ICl 或 IBr)的结合有效促进了 α-唾液糖苷化。
