✦ Synopsis

We use the chamigrene numbering for the structural formulae and spectroscopic data; IUPAC nomenclature and numbering are used for retrieval purposes. ' ) 4, The structural assignment of (-)-5 rests on the enone UV absorption at 1 , , , 325 and 240 nm and on NMR data for two conformers resulting from flipping of the enone ring (Exper. Part). The 'H-NMR spectra are fully assigned for both conformers of (+)-6, resulting from flipping of the diene ring (Exper. Part).
