The DDQ mediated oxidative cyclisation reactions of a series of dihydronaptho[2,1-b]furans were examined. In the presence of an acid catalyst, the reaction yielded polycyclic ethers and lactones in good to excellent yields. (C) 2005 Elsevier Ltd. All rights reserved.

A new practical synthesis of functionalised 1,2-dihydronaphtho[2,1-b]furans from substituted 2,4a-dihydronaphtho[2,1-c][1,2]dioxines and stabilised phosphorus ylides is described. Functionalised γ-hydroxy enones and their isomeric hemiacetals are key intermediates.
