Altho,gh very prominant in bicycloC2.2.llheptadiene photochemistry; the difficulty of observing Cristol closure (internal 2 + 2 cycloaddition) with bicyclo[2.2.2]octodienes has been surprising to many workers.1 Recently, however, Prinzbach, Eberbach, and PhillipposianZ have isolated the Cristol clos

## Abstract The reduction of __cis__‐4 a‐methyl‐1,2,4a,7,8,8 a‐hexahydronaphthalene‐2,7‐dione (**1**) was studied by cyclic voltammetry and product analysis. On a preparative scale, 6‐hydroxy‐3‐methyltetracyclo[4.4.0.0^2,4^.0^3,8^]decan‐10‐one (**2**) was obtained in 22% yield __via__ an intramolec
The reaction of photoisomerization of norbornadiene and its derivatives to the corresponding quardricyclanes, brought about either by direct irradiation or triplet sensitization is well known (1). However, similar isomerizations involving the related bicyclo[2.2.2]octa-2,5-diene system are not known
