(-)-(2R)-Cyclamen
aldehyde - cyclamen-like odor; also described as
"green, floral, cyclamen" (Yamamoto)
=
(2R)-(-)-3-(4-isopropylphenyl)-2-methylpropanal
Ref: Hamada,
Kazuhiko; Production of optically active
cyclamen aldehyde, Japanese Patent No. 55027166,
Feb. 27, 1980; T. Yamamato, Advances in the
transition metal (Rh, Ru)-BINAP-catalyzed
asymmetric chiral compounds for flavours and
fragrances and their associated sensory
properties, in Current Topics in Flavours and
Fragrances - Towards a New Millennium of
Discovery, Karl A. D. Swift, Ed., Kluwer
Academic Publishers (now Springer), 2000, pp.
33-59, Note that the odor description is based
on the (-)-enantiomer as Yamamoto's assignment
of the (R) configuration appears to have been
reversed.

(+)-(2S)-Cyclamen
aldehyde - lily bell-like odor; also described
as "ozone-like, aldehydic, chemical"
(Yamamoto)

on the (+)-enantiomer as Yamamoto's assignment
of the (S) configuration appears to have been
reversed.
