The synthesis of three heterocycles 1–3 presenting identical faces containing a hydrogen bonding code for self-assembly is described. Pyrimidoquinazolinetetrone 1 and diaminopyrimidoquinazolinedione 2 were approached using a double Chapman rearrangement followed by closure to the double uracil-type structure 1. Diaminopyridoisoquinolinedione 3 was obtained in three steps from pyromellitic anhydride
描述了三个杂环1–3的合成,这些杂环具有相同的面,其中包含用于自组装的氢键键。使用双查普曼重排法接近嘧啶基喹唑啉四酮1和二氨基嘧啶基喹唑啉二酮2,然后闭合至双尿嘧啶型结构1。从苯均四酸酐中分三步得到二氨基吡啶基异喹啉二酮3。
