Description
- General description: (-)-Menthol is a monoterpene.[1]
- Application: (-)-Menthol may be used to synthesize: chiral enantiopure 2-(1-hydroxyalkyl)pyridines, which can react with phosphorus oxychloride to form C3-symmetric tripodal ligands[2]menthylphosphorodichioridite, a chiral derivatizing agent for the determination of enantiomeric purity of chiral diols or diamines by 31P NMR spectroscopy[3](2R,4S)-2,3,4,5-tetrahydro-2-(-)-menthyloxy-2-methyl-4-phenylpyrano-[3,2-c]-benzopyran-5-one, an intermediate to prepare a warfarin analog[4]It may also be used as a chiral auxiliary, to induce chirality while synthesizing (-)-horsfiline.[5]
