The epoxidation of quinone rings of calixquinones represents a valid route for the introduction of oxygenated functionalities into the de-tert-butylated calixarene walls originating cis-diepoxy-p-dione moieties. Carbonyl reduction of these systems leads to hybrid calixarenes containing dianhydroinositol moieties (calixinositols) belonging to the calixcyclitols family. The regio- and stereochemistry
