Abstract:
This paper presents a QSAR study for 15 sandalwood odour compounds with rigid structure having qualitatively defined odour. An equation obtained by classic MLR procedure resulted for δ (the presence of the osmophoric group in the extreme axial position of the decaline rest) and D (the distance between the osmophoric group and the hydrophobic moiety of the molecule) as structural parameters, give a good correlation coefficient (r = 0.934); another equation using δ, D and MTD as structural parameters show a very good correlation coefficient (r = 0.984). A hypothetical model for the sandalwood odour receptor site with Dopt = 3.5 Å is proposed.
