The present invention is directed to a process for the preparation of β-lactams. Generally, an imine is cyclocondensed with a ketene acetal or enolate to form the β-lactam product in a “one pot” synthesis, this process is generally performed at a higher temperature than conventional processes.
本发明涉及一种制备β-内酰胺的方法。通常,
亚胺与酮
乙缩醛或烯醇酸盐进行环缩合成β-内酰胺产物,这种“一锅法”合成过程通常在比传统工艺更高的温度下进行。
