The synthesis of a newclass of chiral pentacycloundecane cage annulated macrocycles is reported. The ability of the chiral hosts to transport racemic phenylglycine methyl ester enantioselectively through a chloroform membrane in a U-tube was compared to that of related pyridine macrocycles. The cage annulated macrocycles showed weak to moderate enantioselectivity and very high rates of transport compared
