Ambroxide, widely known by the brand name Ambroxan, is a naturally occurring terpenoid and one of the key constituents responsible for the odor of ambergris. It is an autoxidation product of ambrein.{{citation | author=Karl-Georg Fahlbusch | contribution=Flavors and Fragrances | title=Ullmann's Encyclopedia of Industrial Chemistry | edition=7th | publisher=Wiley | year=2007 | page=72|display-authors=etal}} Ambroxide is used in perfumery for creating ambergris notes and as a fixative. Small amounts (< 0.01 ppm) are used as a flavoring in food.{{citation|author=George A. Burdock|title=Fenaroli's Handbook of Flavor Ingredients|page=1895|year=2010|edition=6th|publisher=CRC Press|entry=1,5,5,9-TETRAMETHYL-13-OXATRICYCLO-(8.3.0.0(4,9)) TRIDECANE}}
Synthesis
Ambroxide is synthesized from sclareol, a component of the essential oil of clary sage.{{cite book | title = Essential Oils 1995-2000 | author = Brian M Lawrence | year = 2003 | publisher = Allured Pub. | isbn = 0-931710-94-4}} Sclareol is oxidatively degraded to a lactone, which is hydrogenated to the corresponding diol.{{cite journal |doi=10.1038/s41570-018-0049-z|title=The role of the metal-bound N–H functionality in Noyori-type molecular catalysts|year=2018|last1=Dub|first1=Pavel A.|last2=Gordon|first2=John C.|s2cid=106394152|journal=Nature Reviews Chemistry|volume=2|issue=12|pages=396–408}} The resulting compound is dehydrated to form ambroxide.
