What is Rose Oxide?

The name β€œRose oxide” was originally applied to a formerly unknown material, isolated in 1959 from Bulgarian Rose oil which contained at least two stereo-isomerides of this formula.

The first synthetic β€˜β€œRose oxide” was a mixture of several isomers, and today many years later, a pure single isomer is still a rare material!

The preferred isomer of the molecule would be Cis-2-(2-Methyl-l-Propenyl)-4-methyltetrahydropyran.

Some differences between the Laevo and the Dextro isomers.

The dextro-cis and the dextro-trans forms are exclusively synthetic.

The laevo-cis and the Iaevo-trans forms may be either synthetic or natural.
