Compound: (R)-4-Hydroxydihydrofuran-2(3H)-one, is researched, Molecular C4H6O3, CAS is 58081-05-3, about Synthesis of (S)-N-(benzyloxy)-4-(acetoxymethyl)-2-azetidinone, a potential intermediate for carbapenem antibiotics, by a chemomicrobiological approach. Author is Yamada, Haruo; Sugiyama, Hajime; Kajiwara, Masahiro.
(R)-Me3COCH2CH(OH)CH2CO2Et, which was prepared by Bakers’ yeast reduction of Me3COCH2COCH2CO2Et, was converted to (R)-3-hydroxybutyrolactone. After cleavage of the lactone ring with PhCH2ONH2, β-lactam cyclization of the hydroxamate was carried out by the Mitsunobu procedure with complete inversion of configuration at C-3 to give (S)-N-benzyloxy-4-acetoxymethyl-2-azetidinone (I). The (R)-azetidinone was also synthesized from (S)-malic acid via (S)-3-hydroxybutyrolactone.
