title: Studies towards the synthesis of bielschowskysin. Construction of the highly functionalized bicyclo[3.2.0]heptane segment.
abstract: A stereocontrolled approach for the construction of a highly functionalized bicyclo[3.2.0]heptane derivative embodying the bridged lactone present in the diterpene bielschowskysin is reported. The key step involves a stereoselective Cu(I)-catalyzed [2 + 2] photocycloaddition of a 1,6-diene embedded in a sugar derivative.
