✦ Synopsis

A new synthesis of tricyclic sesquiterpene, sterpurene 1 is reported. An intermolecular [2+2]-photocycloaddition 1415 serves as a key step, which is promoted through the stabilisation of the enone excited state through a b-carbomethoxy substituent on the a,b-unsaturated enone moiety. A tricyclo[6.3.0.0 3,6 ]undecane based advanced intermediate 19 en route to 1, has been fragmented to the bicyclo[6.3.0]undecane system 27 present in the asteriscane-type sesquiterpenoids.
