Provided are methods for the preparation of glycosylation products, including those represented by formula I:
Sugar-O—R′ I
comprising the step of combining R′—OH, a glycosyl sulfide glycosyl donor (“thioglycoside donor”), a hypervalent iodine alkyl-transfer activating reagent, and a base. In an embodiment, the hypervalent iodine alkyl-transfer activating reagent is (phenyl(trifluoroethyl)iodonium triflimide).
提供了制备糖基化产物的方法,包括由式I表示的那些:
糖-O—R′ I
包括将R′—OH、糖基硫醚糖基供体(“硫代糖苷供体”)、高价碘烷基转移活化试剂和碱结合的步骤。在一种实施例中,高价碘烷基转移活化试剂为(苯基(三氟乙基)碘三氟甲磺酰胺)。
