A new synthetic method for the preparation of high enantiopure (R)-2-((2-oxooxazolidin-5-yl)methyl)isoindoline-1,3-dione has been developed. The enantiopurity of the obtained (R)-2-((2-oxooxazolidin-5-yl)methyl) isoindoline-1,3-dione is established using chiral high performance liquid chromatography (HPLC)i.e. enantiomeric excess (ee) as 100%. One among the two proposed approaches, is succeeded in preparing enantiopure targeted chiral building block using (R)-2-(chloromethyl)oxirane ((R)-epichlorohydrin) as precursor. This heterocyclic 2-oxazolidinone moiety could be useful to prepare a series of antibacterial agents containing 2-oxazolidinone.
已开发出一种新的合成方法,用于制备高对映纯度的(
R)-2-((2-oxooxazolidin-5-yl)methyl)isoindoline-1,3-二酮。所得的(
R)-2-((2-oxooxazolidin-5-yl)methyl)isoindoline-1,3-二酮的对映纯度是通过手性高效
液相色谱(HPLC)确定的,即对映体过量(ee)为100%。在提出的两种方法中,有一种成功地利用(
R)-
2-(氯甲基)环氧乙烷((
R)-
环氧氯丙烷)作为前体制备了高对映纯度的靶向手性构建块。这种杂环2-氧杂氮烷酮基团可用于制备一系列含有2-氧杂氮烷酮的抗菌剂。
