An efficient preparation of 6~(I,IV) dihydroxy permethylated beta-cyclodextrin

摘要

We report on a straightforward synthesis of 2~(I-VII),3~(I-VII),6~(II,III,V-VII)-nonadeca-O-methylcyclomaltoheptaose,a methylated beta-cyclodextrin derivative bearing two 6~(I,IV) hydroxyl groups,from its easily available benzylated counterpart.
