The carbocyclic [3n]metacyclophanes 3, 4, 5 are obtained for the first time, using (p-tolylsulfonyl)methyl isocyanide (TosMIC, 2) as the cyclization reagent. A new cyclization procedure without phase-transfer conditions was applied. One of the resulting intraannular substituted oligoketones, 3, was transformed into the corresponding dialcohol 6.
