Abstract
Abstract MCPBA promoted epoxidation of the C(9)-C(10) double bond in endo -tricyclo [6.2.1.0 2,7 ]undeca-4, 9-diene-3,6-dione ( 4 ) followed by intramolecular [2 + 2] photocyclization of the resulting exo epoxide ( 5 ) afforded the title compound, 1 , in 16% overall yield. The structure of symmetrically hydrated 1 (i.e., 1a ) was determined by single crystal X-ray crystallographic methods. Proton and carbon-13 NMR spectral assignments are given for epoxide 5 .
