The Uses of Methyl (R)-(+)-lactate
(+)-Methyl D-lactate can be used as a starting material in the asymmetric preparation of:
- Neomethymycin, a macrolide which contains 12-membered macrolactone that is used as a potent biological agent.
- PM-toxin A.
It can also be used as a chiral pool along with D-(-)-tartaric acid in the stereoselective total synthesis of separacenes A and B via Trost-Rychnovsky alkyne rearrangement, Horner-Wadsworth-Emmons olefination as well as Corey-Bakshi-Shibata reaction.
Definition
ChEBI: A methyl lactate that has R configuration.
General Description
This compound has benign qualities and is biodegradable, water miscible, and functions as a versatile solvent for CA membrane preparation. This is also used as an intermediate for the production of other chemicals, polymers, and derivatives. Thus this product has been enhanced for Safer solvents and auxiliaries.
