Preparation

Prolinol is obtained by reduction of the amino acid proline using lithium aluminium hydride.[2][3] Because proline is cheaply available in high optical purity, enantiomerically pure prolinol is also widely available.

Use

Prolinol is used in broad variety of chemical reactions as chiral ligand, chiral catalyst or chiral auxiliary reagent in the Hajos–Parrish–Eder–Sauer–Wiechert reaction, the Baylis–Hillman reaction, Noyori type reactions and the Michael reaction. [4][5]
