Abstract
The chiral isomers of 3,3-dimethyl-5-(2,2,3-trimethyl-3-cyclopenten-1-yl)-4-penten-2-ol and, more particularly, the (-)-(1'R,2S,E)-3,3-dimethyl-5-(2',2',3'-trimethyl-3'-cyclopenten-1'-yl)-4- penten-2-ol and (+)-(1'S,2S,E)-3,3-dimethyl-5-(2',2',3'-trimethyl-3'-cyclopenten-1'-yl)-4- penten-2-ol, are useful as perfuming ingredients to impart sandalwood type odor notes to the perfuming compositions and perfumed articles into which they are incorporated.
