Description

General description

Isopulegol is monoterpene alcohol, a useful ingredient for the production of fragrances in perfume industries. It is also used as a starting material in the manufacture of menthol by the hydrogenation process. Menthol is an important component in cosmetics, pharmaceuticals, and toothpaste.

Application

(−)-Isopulegol can be used as a starting material for the enantioselective preparation of:      

• 8-arylmenthols by Smiles-Truce rearrangement of aryl sulfonates.,·        
• Stereoisomers of 5,9-dimethylpentadecane.
• Octahydro-2H-chromen-4-ol by Prins cyclization with vanillin in the presence of montmorillonite clay as the catalyst.     
• p-menthane-3,8,9-triol by catalytic Sharpless dihydroxylation.
