Abstract

Abstract: A series of silicon‐containing derivatives of linear alicyclic musks comprising sila‐Rosamusk (3b ), sila‐Romandolide (5b ), sila‐Applelide (11b ), and the corresponding dehydro derivatives was synthesized from sila‐analogs of Artemone and Herbac, respectively, by means of sodium borohydride reduction and subsequent esterification with the corresponding acid chlorides in the presence of triethylamine. The olfactory properties of the new sila‐odorants3b –13b are reported in comparison with their carba‐analogs3a –13a, and quantitative threshold data allowed the generation of an improved musk olfactophore model featuring a correlation of 80.5 % with a null‐cost distance of 244. This olfactophore model shows that it is likely that linear and macrocyclic musks address the same odorant receptors, and it should facilitate the design of new musks. Abstract : Sila‐Rosamusk, sila‐Romandolide, sila‐Applelide, and their dehydro derivatives were synthesized from sila‐analogs of Artemone and Herbac by hydride reduction and subsequent esterification. The olfactory properties of these compounds allowed a refined musk olfactophore model to be developed. The model shows that it is likely that linear and macrocyclic musks address the same odorant receptors.
