✦ Synopsis

A novel cyclodextrin derivative: mono(6 A -N-allylamino-6 A -deoxy)perphenylcarbamoylated b-cyclodextrin was synthesized. Hydrosilylation with (EtO) 3 SiH and then reaction of the reactive siloxane with pristine silica gel afforded a facile entry into a durable, structurally well-defined chiral stationary phase capable of enantioseparation of a variety of racemic drugs.
