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 (R)-Ethyl 4-tert-butoxy-3-hydroxybutanoate, a versatile chiral building block for EPC (enantiomerically pure compound) syntheses, by yeast reduction of ethyl 4-tert-butoxy-3-oxobutanoate. Author is Seebach, Dieter; Eberle, Martin.
Treatment of ROCH2COCH2CO2R1 (I; R = Me3C, R1 = Et) with baker’s yeast and sucrose in H2O at 28° for 4 days gave 72% (R)-ROCH2CH(OH)CH2CO2R1 (II; R = Me3C, R1 = Et) in 97% enantiomeric excess. Similar treatment of I (R = Me3C, R1 = Me; R = PhCH2, R1 = Et) gave 70 and 58% II in 82 and 56% enantiomeric excess resp.
