SYNTHESIS OF NATURALLY-OCCURRING (-)-DELTA-9(12)-CAPNELLENE AND ITS ANTIPODE - AN APPLICATION OF THE PHOTOINDUCED VINYLCYCLOPROPANE-CYCLOPENTENE REARRANGEMENT
Abundantly available (+)-DELTA-3-Carene, 1 has been transformed into enantiomerically pure key intermediates viz. the enones (-)-7 and (+)-7, thus constituting a formal synthesis of both the enantiomers of DELTA-9(12)-Capnellene.
