Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (R)-4-Hydroxydihydrofuran-2(3H)-one, is researched, Molecular C4H6O3, CAS is 58081-05-3, about Taming carbohydrate complexity: a facile, high-yield route to chiral 2,3-dihydroxybutanoic acids and 4-hydroxytetrahydrofuran-2-ones with very high optical purity from pentose sugars.Application of 58081-05-3.
(S)-3,4-Dihydroxybutanoic acid and its γ-lactone [(S)-4-hydroxytetrahydrofuran-2-one] are important four-carbon synthons obtainable from some substituted D-hexose sugars and from L-malic acid. Until now there has been no easy route to the R-isomers because of the rarity both of suitably substituted L-hexose sugars and D-malic acid. Here we describe a method for preparing both enantiomeric forms of the free acids and their corresponding γ-lactones from pentose sugars.
The article 《Taming carbohydrate complexity: a facile, high-yield route to chiral 2,3-dihydroxybutanoic acids and 4-hydroxytetrahydrofuran-2-ones with very high optical purity from pentose sugars》 also mentions many details about this compound(58081-05-3)Application of 58081-05-3, you can pay attention to it, because details determine success or failure
