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