Reference of (R)-4-Hydroxydihydrofuran-2(3H)-one. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: (R)-4-Hydroxydihydrofuran-2(3H)-one, is researched, Molecular C4H6O3, CAS is 58081-05-3, about Inversion of configuration of (S)-β-hydroxy-γ-butyrolactone with total retention of the enantiomeric purity. Author is De Angelis, Francesco; De Fusco, Enrico; Desiderio, Paola; Giannessi, Fabio; Piccirilli, Fabrizio; Tinti, Maria Ornella.
The inversion of configuration of (S)-β-hydroxy-γ-butyrolactone to its (R) enantiomer is reported with total retention of the enantiomeric purity by a 4-step procedure. The (R) enantiomer was thus synthesized with an overall chem. yield of 47% and >97% ee. This transformation opens an economic route to the production of (R)-GABOB and (R)-carnitine, among other biol. active compounds, from a D-hexose source, or, alternatively, from the industrial waste compound (S)-carnitine. During the reaction sequence, the intermediate (R)-β-(hydroxymethyl)-β-propiolactone is also prepared, which is now under investigation as a chiral synthon for new synthetic applications.
