(+)-ISOPINOCAMPHEOL

(1S,2S,3S,5R)-(+)-Isopinocampheol may be used in the preparation of

• thermotropic chiral nematic side-chain copolymers
• ortho-(diphenylphosphino)phenylphosphonous acid di[(1S,2S,3S,5R)-2,6,6-trimethyl-bicyclo[3.1.1]-hept-3-yl]ester, a phosphino-phosphonite ligand
• O,O′bis[(1S,2S,3S,5R)2,6,6-trimethylbicyclo[3.1.1]hept-3-yl] dithiophosphoric acid, a bioactive compound with antifungal effect

(1S,2S,3S,5R)-(+)-Isopinocampheol is a chiral terpenol.

Dissolve it in Et2O, dry over MgSO4, filter, evaporate, then recrystallise it from pet ether. Also recrystallise it from aqueous EtOH and distil it in a vacuum.
