摘要
Naturally occuring cyclodextrins show only limited enantioselectivity in their interactions with chiral guests, because they form inclusion complexes in which there is only limited interaction between chiral centres of the cyclodextrin and those of the guest. As the extent of interaction between these groups is increased, as a result of modification to the cyclodextrin, the stereoselectivity is often increased. Additional secondary bonding interactions, complexation to metallocyclodextrins and covalent host-guest interactions all lead to enhanced chiral discrimination.
