Use

Nerolidol is the sesquiterpene analog of linalool. Because of the double bond at the 6-position, it exists as (6Z)- and (6E)- isomers, each forming an enantiomeric pair, since the carbon atom in the 3-position is asymmetric. Nerolidol is a component of many essential oils. (3S,6E)-(+)-nerolidol occurs in cabreuva oil. Synthetic nerolidol consists of a mixture of racemic (6Z)- and (6E)-nerolidol and is a colorless liquid with a long-lasting, mild floral odor. Industrial synthesis of nerolidol starts with linalool, which is converted into geranylacetone by using diketene, ethyl acetoacetate, or isopropenyl methyl ether, analogously to the synthesis of 6-methyl-5-hepten-2-one from 2-methyl- 3-buten-2-ol. Addition of acetylene and partial hydrogenation of the resultant dehydronerolidol produces a mixture of (6Z)- and (6E)-nerolidol racemates.Nerolidol is used as a base note in many delicate floral odor complexes. It is also an intermediate in the production of vitamins E and K1.
