collective synthesis of rhynchosporosides causing scald diseases has been achieved, which features orthogonal one-pot glycosylation on the basis of PTFAI glycosylation, Yu glycosylation, and PVB glycosylation and merging reagent modulation and remote anchimeric assistance (RMRAA) α-glucosylation strategies. The issues inherent to the thioglycoside-based orthogonal one-pot glycosylation strategy, such as
以PTFAI糖基化、Yu糖基化、PVB糖基化为基础的正交一锅法糖基化以及合并试剂调控和远程非嵌合辅助(RMRAA)α-糖基化策略,实现了高效、集体合成引起烫伤病的钩孢子苷。基于硫糖苷的正交一锅糖基化策略所固有的问题(例如糖苷配基转移)已被这种正交一锅糖基化策略排除,该策略可以简化聚糖的化学合成。
