Chemical compound

Isoborneol is a bicyclic organic compound and a terpene derivative. The hydroxyl group in this compound is placed in an exo position. The endo diastereomer is called borneol. Being chiral, isoborneol exists as enantiomers.

Preparation

Isoborneol is synthesized commercially by hydrolysis of isobornyl acetate. The latter is obtained from treatment of camphene with acetic acid in the presence of a strong acid catalyst.

It can also be produced by reduction of camphor:

Isoborneol derivatives as chiral ligands

Derivatives of isoborneol are used as ligands in asymmetric synthesis.
