Using thioglycosides as donors, trimethylsilyl trifluoromethanesulfonate (TMSOTf) and N-iodosuccinimide(NIS) as promoter, a modified procedure for the glycosylation of spirostanol was developed. A series of saponins were synthesized in mild condition with excellent yields.
- Spirostanol glycoside,
- glycosylation,
- trimethylsilyl trifluoromethanesulfonate,
- ethyl 1-thioglycoside,
- N-iodosuccinimide
