6-Isopropyldimethylsilyl-2,3-diethylbetacyclodextrin useful for optical isomer separation and its preparation method

摘要

The present invention relates to a -cyclodextrin derivative, more particularly, to a -cyclodextrin derivative useful for optical isomer separation, wherein an isopropyldimethylsilyl group is introduced into the carbon at the 6-position and ethyl Is introduced, which is used as a stationary phase of the CGC column in the separation of the racemic optically active substance.;The present invention also provides a method for producing the above-mentioned -cyclodextrin derivative and a method for separating an optical isomer using such a derivative.
