L-threo-Hex-2-enaric acid 1,4-lactone 6-methyl ester(CAT: R025424) is a stereochemically defined unsaturated carbohydrate derivative featuring a lactone ring with a methyl ester group at the 6-position. The L-threo configuration and presence of an α,β-unsaturated system make it a valuable intermediate in the synthesis of natural products, nucleoside analogs, and glycomimetic compounds. Its functionalized sugar-like structure is suited for applications in medicinal chemistry, particularly in the design of enzyme inhibitors and bioactive small molecules. The compound’s conjugated system and protected functionalities also support selective transformations, making it a useful scaffold in synthetic organic and carbohydrate chemistry.
