Cyclocondensation of 6-amino-2,4-dioxopyrimidine or 2,4,6-triaminopyrimidine with 1-cyclohexenecarbox-aldehyde 13 afforded regiospecifically, tricyclic, angular 1,3-disubstituted tetrahydropyrimido[4,5-c]isoquin-olines 5 and 6 respectively. In addition, 2,4,6-triaminopyrimidine when condensed with 2-chloro-1-cyclohex-enecarboxaldehyde 14, regiospecifically afforded the angular isomer 6. However, the
6-氨基-2,4-二氧嘧啶或2,4,6-三氨基嘧啶与1-环己烯甲醛13的环缩合反应可以区域特异性地形成三环,有角的1,3-二取代的四氢嘧啶[4,5 - c ]异喹啉5和6个。此外,当与2-氯-1-环己烯-甲醛14缩合时,2,4,6-三氨基嘧啶,区域特异性地提供了角异构体6。然而,2,6-二氨基-4-氧嘧啶与13的环缩合是区域选择性的,并提供线性和有角的四氢嘧啶异喹啉2和4的混合物。。在9×10 -8 M,白血病L-1210细胞在培养物中的生长被6抑制了50%。化合物4和5没有明显的活性。
