Synthesis route :
The synthesis of Exaltolide® can be done in two major ways. One is to enlarge the cycle size of cyclododecanone. A radical addition of allyl alcohol to this starting reagent, in the presence of a peroxide, allows to implant an alcohol function linked to a carbon chain on the starting molecule. An acidic catalysis enables a dehydration of the intermediate product. Then, an addition of hydrogen peroxide in an acid medium to the molecule obtained in the previous process, followed by a heating of the last intermediate in xylene, allows the synthesis of Exaltolide®. The second synthesis route is made from polyesters of 15-hydroxypentadecanoic acid (which is prepared by a rather complex first process), placed under a high vacuum and in the presence of a trans-esterification catalyst.
Synthesis precursor :
Exaltolide® is not a precursor to the synthesis of another compound of olfactory interest.
