Recently, we reported the conversion of 2-fonqyl-3-keto-9-methyl-Al,4 -hexahydronaphthalene into a perhydroazulene derivative by irradiation in aqueous acetic acid followed by base treatment of the photo-product (1). We now have found that L4 2-carboxy-3-keto-g-methyl-A -hexahydronaphthalene (I) is
We have found that on irradiation in aqueous acetic acid followed by base catalyzed defomylatlon of the c-de photo-product, the 2-fonqyl dienone III is converted into the5/7-fused dienone IV in 7% overall yield. Ccmpound III was prepared from the octalone I (1) by a procedure similar to that employ
