We have developed the synthesis of twenty four new iminolactones, bis-iminolactones and bis-lactones by subsequent esterification–condensation or addition–condensation reactions according to two strategies from α-hydroxyketones. The X-ray diffraction data of a bis-iminolactone is described and present an interesting helical column packing.
根据α-羟基酮的两种策略,我们通过随后的酯化-缩合或加成-缩合反应,开发了二十四种新的亚氨基内酯,双亚氨基内酯和双内酯。描述了双亚氨基内酯的X射线衍射数据,并给出了令人感兴趣的螺旋柱填料。
