Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Tetrahedron called Enantiomerically pure β,γ-epoxyesters from β-hydroxylactones: synthesis of β-hydroxyesters and (-)-GABOB, Author is Larcheveque, M.; Henrot, S., which mentions a compound: 58081-05-3, SMILESS is O=C1OC[C@H](O)C1, Molecular C4H6O3, HPLC of Formula: 58081-05-3.
The preparation of enantiomerically pure β,γ-epoxy esters was achieved by chemoselective opening of β-hydroxybutanolides with Me3SiI followed by cyclization of the resulting iodohydrins with Ag2O. The reaction of these epoxy esters with lithio- or magnesiocuprates afforded stereochemically pure α-substituted-β-hydroxy esters. Alternatively, the title compound, (R)-H2NCH2CH(OH)CH2CO2H, was synthesized in optically pure form from the iodohydrin (R)-ICH2CH(OH)CH2CO2Et.
Compounds in my other articles are similar to this one((R)-4-Hydroxydihydrofuran-2(3H)-one)HPLC of Formula: 58081-05-3, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
