4-acyloxy-azetidinones in the presence of Lewis acids can be used to alkylate nucleophilic arenes in both the inter- and intramolecular processes. The former reactions were successfully carried out with p-dimethoxy-benzene in moderate yield, whereas the latter reactions can be done with a variety of nucleophilic arenes in a good yield.
在路易斯酸存在下衍生自4-酰氧基-氮杂环丁烷酮的酰基酰亚胺阳离子可用于在分子间和分子内过程中将亲核芳烃烷基化。前一种反应是用对-二甲氧基苯以中等收率成功进行的,而后一种反应可以用多种亲核芳烃以高收率进行。
