Valinol is an organic compound named after, and commonly produced from, the amino acid valine. The compound is chiral and is produced almost exclusively as the SâÂÂisomer (also designated as the LâÂÂisomer), due to the abundant supply of S-valine. It is part of a broader class of amino alcohols.
Valinol can be generated by converting the carboxylic group of valine to an alcohol with a strong reducing agent such as lithium aluminium hydride, or with NaBH<sub>4</sub> and I<sub>2</sub> (forming the boraneâÂÂtetrahydrofuran complex). In both cases the valinol produced can be subsequently purified by short path distillation.
Valinol is mainly used to prepare chiral oxazolines, a process which can be achieved via a variety of methods. These oxazolines are principally used as ligands in asymmetric catalysis.
