Stereocontrolled approach to the highly functionalized bicyclo[3.2.0] heptane core of bielschowskysin through intramolecular Cu(I)-catalyzed [2+2] photocycloaddition
A direct route for the synthesis of highly functionalized bicyclo[3.2.0]heptane core containing the bridged lactone with the functionalized C-12 substituent of bielschowslcysin is reported. The key step involves a stereoselective Cu (I)-catalyzed [2+2] photocycloaddition of a 1,6-diene embedded in a sugar derivative. (C) 2012 Elsevier Ltd. All rights reserved.

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.
