    摘要: A method for obtaining a desired pattern of substitution of hydroxyalkyl groups on cyclodextrins which comprises controlling the basicity of a reaction mixture comprising epoxide and cyclodextrins and a suitable solvent. Through the proper control of basicity with, e.g., sodium hydroxide, hydroxyalkyl substitution may be directed either toward the narrow or wide opening of the cavity of cyclodextrins.
