Some new approaches to the 1,6-methano[10]annulenesystem are described. The routes were used to prepare 1,6-methano[10]annulene-3-acetic acid and the alpha-methyl analog. The compounds showed antinflammatory and analgesic activity, though less than that of corresponding naphthalene compounds; the possible effect of the chirality of the annulene on the observed biological activity is discussed.

The electron transfer photochemistry of three rigid, bridged allylcyclopropane systems 3-carene (1), tricyclo[4.3.1.0(1.6)]dec-3-ene (2) and tricyclo[4.4.1.0(1.6)]undeca-3,8-diene (3), is shown to take an unprecedented course: the major products are novel 'substitution' products, in which a hydrogen at an allylic carbon (C-2) Of the substrate has been replaced by the p-cyanophenyl group.
