Preparation edit

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.[2]

It can also be produced by reduction of camphor:

 

Isoborneol derivatives as chiral ligands edit

Derivatives of isoborneol are used as ligands in asymmetric synthesis.[3]
