The Absolute

(−)-Chenopodanol (2) has been isolated from the liverwort Marchantiachenopoda and its structure determined by spectroscopic techniques as well as by total synthesis. Chenopodene (1) has also been synthesized in an optically active form, resulting in revision of the originally assigned absolute configuration.

Circular Dichroïsm

Racemic 3-ferrocenylalanine was resolved in enantiomers using brucine. The absolute configuration was estimated by ozonolytic degradation of the N-trifluoroacetyl derivative of the (-)-enantiomer yielding D-aspartic acid. Diastereoisomeric cyclo(D-ferrocenylalanyl-L-prolyl) and cyclo-(L-3-ferrocenylalanyl-L-prolyl) were synthesized using conventional methods of peptide synthesis. Circular dichroism spectra of these cyclodipeptides are discussed and compared with spectra of the corresponding diastereoisomeric cyclodipeptides containing phenylalanine.
