Applications

L-(+)-Valinol reacts with aldehydes and nitriles to form imines and oxazolines, respectively, for asymmetric synthesis. It is also used for preparation of 4-isopropyloxazolidinones, employed in stereocontrolled aldol and alkylation reactions, synthesis of chiral 2-thiazolidinethiones for aldol reactions, asymmetric alkylation of condensation product with keto acids, asymmetric reactions of its amidines and imines and oxidation of N-protected derivative to the aldehyde.

Notes

Keep container tightly sealed. Store in cool, dry conditions in well sealed containers. Incompatible with oxidizing agents. It is sensitive to air. Store under dry inert gas.
