The action of boiling acetic anhydride on β-ureidesters, β-N-carbonyl esters and β-amino-esters was studied. It was shown that no cyclization of β-ureidoesters occurred and that N,N-diacetyl and N-acetyl-β-aminoesters were the reaction products in all three cases. A satisfactory separation of these compounds by chromatography was achieved and their physical properties determined. The mechanism of the
研究了乙酸酐沸腾对β-脲酯,β-N-羰基酯和β-氨基酯的作用。结果表明,没有发生β-脲基酯的环化,并且在所有三种情况下,N,N-二乙酰基和N-乙酰基-β-氨基酯都是反应产物。通过色谱法令人满意地分离了这些化合物,并确定了它们的物理性质。简要讨论了反应机理。
