Stereospecific Synthesis of (+)-β-Sesquiphellandrene
摘要:
The structure and absolute configuration of (-)-beta-Sesquiphellandrene ((-)-1a) is shown to be (6S)-2-methyl-6-[(1'R)-4-methylidcnecyclohex- 2-enyl]hept-2-ene by stereospecific synthesis of its enantiomer ((+)- 1a) and of a further (6S,1'S)-diastereoisomer ((+)-1b). Characteristic spectroscopic differences in both diastereoisomeric series are discussed.
