Uses in perfumery :
Iso E Super® is used in masculine, woody and ambery notes as a woody base. Allows to bring a light violet flower note to woody accords.
Natural availability :
Iso E Super® is not available in its natural state.
Year of discovery :
Discovered in 1956. Iso E Super® was first patented in 1973, by scientists John B. Hall and James M. Sanders.
Other comments :
The name of Iso E Super® comes from the contraction of ISOcyclomyrcetone Ethanone, and the SUPERior quality which has been made accessible since the improvement of the manufacturing process. Often called 'bois-violette'.
From 1993, each company was free to produce its own Iso E Super®. The current production of the molecule is 1800 tons per year.

Synthesis route :
Iso E Super® is synthesized by a Diels-Alder reaction between Myrcene and 3-methyl-3-penten-2-one in the presence of aluminum chloride. The cyclization of the intermediate product obtained is made thanks to the action of phosphoric acid. This cyclization gives birth to two isomers : Iso E Super® and Arborone, in 95/5 proportions.
Synthesis precursor :
Iso E Super® is not a precursor to the synthesis of another compound of olfactory interest.
Isomerism :
Iso E Super® is composed by more than 20 isomeric molecules. The molecule called Isocyclemone in its pure state, has almost no smell, but the Iso E Super® called '' Plus '', so-called Arborone, found at between 2 and 5% in the commercialised Iso E Super®, has a very strong smell (10 000 times more powerful than Iso E Super), and is responsible for the smell of Iso E Super®. Iso E Super® Plus alone is not marketed because its production is too expensive.
