✦ Synopsis

The recent communication by Shani (1) in which the photolysis of cis, cis-cyclodeca---3,8-diene-1, 6-dione (I) is reported to give cis,*, cis-tricyclo[5. 3. 0. 0 2, (+d ecane-4,9--dione prompts us to report results we had obtained independently which lead to the cis, -anti, cis (IIa) stereochemical assignment. --In our hands, using acetone as solvent and sensitizer, IIa (60%) along with three other products, was obtained after irradiating I for 2.5 hours (2). Under other conditions, as many as 10 different products have been shown to be present; of these only IIa, cis, trans-I, --

The transannular photocyclization of the cis,cis-cyclodecs-1,6+lienes to the tricyolo 5.3.0.02p6 --C 3 decane (1) may be explained due to the proximity in space of the two double bonds in the ~~hamnocks conformation I (2).
