Abstract

The woody, ambergris-Iike odor of trans-decalone derivatives of type 5 increases with the introduction of equatorial alkyl substituents in the C(9)-positionand decreases drastically in the corresponding 9-epi derivatives. Complete stereocontrol of odor perception has been observed for the diastereoisomers of y-bicyclohomofarnesal 1 and 2. A similar tendency in odor perception has been recognized in substituted alcohols of type 12. The sandalwood- like ambergris note found in Polywood'": (14) disappeared in corresponding alkyl substituted acetates. The molecular basis of the 'steroid-type' scent of some esters of type 39 was hitherto unknown.
