Description and Uses

L-lactide (3,6-dimethyl-1,4-dioxane-2,5-dione) is a cyclic lactone that is derived from lactic acid. It has the molecular formula C3H6O2 and is an essential building block for synthesizing polylactic acid (PLA) plastics, which are widely used in the manufacturing industry.

(3S)-cis-3,6-Dimethyl-1,4-dioxane-2,5-dione may be used in the synthesis of optically active terpyridine containing poly(L-lactide)s, polydisperse lactic acid oligomers, bicyclic and tricyclic lactide derivatives.
