The reaction of N1-sulfonyluracil derivatives bearing a 2-hydroxyethyl moiety at the 3-position with NaH under anhydrous conditions at room temperature affords the corresponding 2-oxazolidinone bearing the β-enaminocarbonyl moiety. These products are useful diversifiable precursors toward various β-amino acids and N-heterocyclic compounds.
在室温、无水条件下,在 3-位带有 2-羟乙基部分的N 1-磺酰尿嘧啶衍生物与 NaH 反应得到相应的带有 β-烯氨基羰基部分的 2-恶唑烷酮。这些产品是各种 β-氨基酸和N-杂环化合物的有用的多样化前体。
