AMBRETTOLIDE Usage And Synthesis
Chemical PropertiesAMBRETTOLIDE is not reported as being found in nature, in contrast to (Z)-7-hexadecen-16-olide, which occurs in ambrette seed oil and which is also referred to as ambrettolide. It is a colorless to slightly yellow liquid, d204 0.949–0.957, n20D 1.477–1.482, with an intense and powerful musk odor. It is prepared by treating aleuritic acid (9,10,16-trihydroxyhexadecanoic acid) with trimethyl orthoformate to give a dioxolane derivative. Reaction with acetic anhydride yields ??-acetoxy (E)-9-hexadecenoic acid methyl ester. This is lactonized with potassium hydroxide to give the title compound .
OccurrenceFound in oil of ambrette seed[Givaudan Index, 1961).
PreparationFrom bromohexadecenoic acid(Bedoukian, 1967).
