摘要：

A variety of 2,5‐dioxacyclohepta[jkl]‐as‐indacenes 5, 7–14 were synthesized as a new heterocycle by the treatment of diethyl (5,9‐dioxobenzocyclohepten‐1,4‐diyloxy)diacetates 4a‐e with potassium hydroxide or sodium hydride in dioxane. The mechanism of furan‐ring formation from 4a‐e was discussed. Copyright © 1990 Journal of Heterocyclic Chemistry
