Synthesis of a novel C<SUB>2</SUB>-symmetrical (2S,5S)-2,5-bis-[(1,1-dimethylethoxy)carbonylamino]-1,6-diphenylhex-3-ene: applications in the synthesis of potential HIV protease inhibitors

The synthesis of a novel and versatile (2S,5S)-2,5-bis-[(1,1'-dimethylethoxy)carbonylamino]-1,6-diphenylhex-3-ene (2) based on Julia's olefination strategy coupled with its application in stereoselective preparations of HIV protease inhibitors has been discussed
