Year of discovery :

Data not available.

Synthesis route :

Cinnamyl Alcohol is synthesized by a reduction of Cinnamaldehyde, the major component of cinnamon essential oil. This can be done in three ways. The Meerwein-Ponndorf reduction (85% yield) reduces the aldehyde in the presence of Benzyl or Isopropyl Alcohol and their aluminum alkoxide. A second reduction is made with a yield of 95%, in the presence of osmium tetroxide. Finally, a last reduction can be made from Cinnamaldehyde in the presence of sodium tetrahydruroborate.

Synthesis precursor :

Cinnamyl Alcohol is a precursor to the synthesis of cinnamyl esters, such as Cinnamyl Acetate or Cinnamyl Benzoate, which are used in perfumery.

Isomerism :

Cinnamyl Alcohol exists as two diastereomers naturally present in nature: the (E) trans form is the most abundant in nature and can be extracted from many plants such as Styrax EO. Cis form is much more powerful (see Other Comments). Ethyl Vanillin is a constitutional isomer of Cinnamyl Alcohol, although their smell is different as Cinnamyl Alcohol is much spicier and less sweet.

Natural availability :

Cinnamyl Alcohol is naturally present in Ceylon Cinnamon EO (and other origins), Peru Balsam Resinoid and Tolu Balsam Resinoid, from which it can be extracted by fractional distillation.

Allergens :

Cinnamyl Alcohol may provoke an allergic reaction on skin contact (redness, heat, scraching, prickling) for some people.
