A new method for the synthesis of azetidine-2,4-diones, involving a Norrish Type II photoreaction of 4-pyruvolyazetidin-2-ones, has been devised. The process features in two strategies in which potassium benzylpenicillinate (17a) is converted into 1-substituted 3-phenylacetamidoazetidine-2,4-diones.
已经设计了一种新的合成氮杂环丁烷2,4-二酮的方法,该方法涉及4-丙酮酸吡喃并ze丁二酮-2-酮的诺里斯II型光反应。该方法以两种策略为特征,其中苄基苄基碳酸钾(17a)被转化为1-取代的3-苯基乙酰氨基氮杂环丁烷-2,4-二酮。
