The asymmetric syntheses of the enantiomers of Madrol(R) (1) are descr
ibed and their odor properties evaluated. (1S)-(-)-1 exerts a powerful
sandalwood odor with some animalic undertones, whereas its antipode s
mells sweet and flowery rather than like sandalwood. Molecular surface
comparisons show remarkable deviations in the hydrophobic parts of th
e two enantiomers. (C) 1997 Wiley-Liss, Inc.
