The ringenlargement of 2-nitrocyclododecanone (1, n = 1) to methyl 2-hydroxy-5-nitrocyclotetradecanecarboxylate (4, n = 1) via 12-hydroxy-1-nitrobicyclo[9.3.1]pentadecane-12-one(2, n = 1) delivered after further transformations in good yield cyclotetradecane-1,4-dione (12). Treatment of this compound with para-toluene sulfonic acid at a Dean-Stark water trap afforded [10](2,5)furanophane (20). In
