A simple and efficient method is proposed for the preparation of a &bgr;-lactam compound such as 1-phenyl-4-ethoxy-2-azetidinone which can be produced by mixing an isocyanate compound such as phenyl isocyanate and a vinyl ether compound such as ethyl vinyl ether and heating the mixture at a moderate temperature under a superatmospheric pressure of up to 12000 atmospheres.
提出了一种简单高效的方法,用于制备β-内酰胺化合物,例如1-苯基-4-乙氧基-2-
氮杂环酮,可以通过混合
异氰酸酯化合物,如苯基
异氰酸酯和乙基
乙烯醚化合物,然后在超大气压下,以高达12000大气压的中等温度下加热混合物来生产。
