(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.
In some applications, this compound(58081-05-3)HPLC of Formula: 58081-05-3 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
