6-DIMETHYLXESILSILYL-2-3-DIETHYLBETACYCLODEXTRIN WHICH IS USEFUL FOR ENANTIOMER SEPERATION AND ITS PREPARING METHOD

摘要

The present invention relates to β-cyclodextrin derivatives, and more particularly, to β-cyclodextrin derivatives useful for optical isomer separation, wherein a dimethyl cesilyl group is placed on carbon at position 6 and an ethyl group is placed at positions 2 and 3 There is provided a new β-CD derivative having the following formula (I) which is used as the stationary phase of a CGC column in the separation of racemic photoactive materials.;The present invention also provides a method for preparing such β-cyclodextrin derivatives and a method for separating optical isomers using such derivatives.
