A simple and efficient protocol for the conversion of N-p-methoxyphenyl, N-p-ethoxyphenyl, N-p-methoxynaphthyl, N-3,4-dimethoxybenzyl and N-p-methoxybenzyl-2-azetidinones to N-unsubstituted 2-azetidinones using cerium(IV) tetrabutylammonium nitrate (CTAN) in dichloromethane is described. The method is compatible with a number of functional groups, and N-unsubstituted 2-azetidinones can be prepared
使用四丁基硝酸铈 (IV) 将 Np-甲氧基苯基、Np-乙氧基苯基、Np-甲氧基萘基、N-3,4-二甲氧基苄基和 Np-甲氧基苄基-2-氮杂环丁酮转化为 N-未取代的 2-氮杂环丁烷酮的简单有效方案(CTAN) 在二氯甲烷中进行了描述。该方法与许多官能团兼容,并且可以在室温下温和条件下制备 N-未取代的 2-氮杂环丁酮。反应迅速,以良好的收率获得纯产物。
