(-)-(1'R)-2-methyl-4-(2',2',3'-
trimethyl-3'-cyclopenten-1'-yl) -4-penten-1-al -
possesses an unexpected odor in view of the
prior knowledge regarding the odor properties of
campholenic aldehyde derivatives. It develops a
woody-sandalwood type odor note, slightly
aldehydic, which is more reminiscent of the
cedar-pine odor connotation than of the
sandalwood type one, which note is combined with
a distinct marine, ozone character. The latter
is reinforced in the bottom note, which is
strongly ozone-marine-like, recalling the odor
of seaweeds. In addition, the odor of this
compound has a good strength and tenacity.
Note that the
C-2 methyl group is epimeric so this is actually
a mixture of the (1'R,2S) and (1'R,2R)
isomers
