3-amino-acridine 1 reacts with formaldehyde in acidic medium to give four different compounds depending on the stoechiometry of the reaction: the dihydrooxazine derivative 2, the tetrahydropyrimidine derivative 3, the Tröger's Base analogue 4 and the acridino[3,4-j]-benzo[b][1,7]phenanthroline 5. Compounds 3, 4 and 5 could be obtained selectively by using the required amount of formaldehyde. Selective synthesis
3-氨基-啶1在酸性介质中与甲醛反应,根据反应的化学计量,生成四种不同的化合物:二氢恶嗪衍生物2,四氢嘧啶衍生物3,Tröger碱类似物4和and啶[3,4-j] -苯并[b] [1,7]菲咯啉5。通过使用所需量的甲醛,可以选择性地获得化合物3、4和5。2的选择性合成以三步顺序独立实现。在12 N HCl溶液中的化合物2、3和4缓慢转化,得到化合物5 作为主要产品。
