## Abstract The title compound **1** is shown to give, both upon direct irradiation at 254 nm and upon acetophenoneβsensitized photolysis at 300 nm, the __syn__βvinylβpentamethylhousene **5**, which spontaneously rearranges in a [3,3]0sigmatropic process to give the bicyclo[3.2.0]heptadiene skeleto
