The features of the synthesis and chemical behavior of some β-cyclodextrin silyl derivatives
摘要:
Conditions are found for the regioselective silylation of the beta-cyclodextrin primary hydroxy groups by diphenylmethylsilyl chloride and trimethylsilyl chloride. It is shown that the position of silyl substituents at the primary or secondary hydroxyl can be determined using Si-29 NMR spectroscopy. In the case of acetic and phosphorous acid chlorides, the subsequent functionalization of the secondary hydroxyls occurs with a significant removal of the protective silyl groups.
