In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called A novel total synthesis of kinsenoside and goodyeroside A relying on the efficient reaction of the chiral 2(5H)-furanones, published in 2005-10-31, which mentions a compound: 58081-05-3, Name is (R)-4-Hydroxydihydrofuran-2(3H)-one, Molecular C4H6O3, Synthetic Route of C4H6O3.
A new total synthesis of the bioactive compounds, kinsenoside (I; R1 = H) and goodyeroside A (II; R2 = H), has been accomplished from readily available starting materials. The chiral 2(5H)-furanone III and its enantiomer IV were employed as the key chiral intermediates to construct the chiral glycosides V and VI with the appropriate stereochem. The spectral data of the target compounds and their acetylated derivatives (I; R1 = Ac) and (II; R2 = Ac) are identical with those of the natural and corresponding acetylated products.
