An electronictopological approach has been used to define an active ambergris
fragment (AAF) which correctly describes the presence (or absence) of the ambergris odour of all
181 compounds investigated. The AAF consists of one oxygen atom and three carbon atoms
(
,ß,
) which are separated by certain key distances and which possess certain
atomic
charges. The C
atom must bear at least one hydrogen atom
(H
) which is located at a certain distance from one of the unshared electronic
pairs of the oxygen
atom.
