설명

일반 설명

(1R,2S,5R)-(-)-Menthol is a monoterpene.

애플리케이션

(1R,2S,5R)-(-)-Menthol may be used to synthesize:

• chiral enantiopure 2-(1-hydroxyalkyl)pyridines, which can react with to form C3-symmetric tripodal ligands
• menthylphosphorodichioridite, a chiral derivatizing agent for the determination of enantiomeric purity of chiral diols or diamines by ³¹P NMR spectroscopy
• (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

It may also be used as a chiral auxiliary, to induce chirality while synthesizing (-)-horsfiline.

Used to prepare reagents for chiral vinylogous Darzens and Reformatsky reactions. Important chiral auxiliary employed in the resolution of acids and for stereocontrolled synthesis.
