Publikováno v: Journal of the Chemical Society. Perkin transactions 1 : organic and bio-organic chemistry. 2001:1353-1358

7H-Naphth[3,2,1-cd]azulen-7-ones are synthesized by the intramolecular Friedel-Crafts cyclization of diethyl 4-phenylazulene-1,3-dicarboxylate derivatives with polyphosphoric acid (PPA). Treatment of 7H-naphth[3,2,1-cd]azulen-7-one with methyl triflu
