Condensation of three 2,4-disubstituted 6-aminopyrimidines with methyl 1-benzyl-4-oxo-3-piperidinecarboxylate afforded, in each case, new tricyclic, angular 1,3,8-trisubstituted pyrimido[4,5-c][2,7]naphthyridin-6-ones. 2,4,6-Triaminopyrimidine gave the 7,8,9,10-tetrahydrocyclo condensed product 5 as anticipated. However, the use of 2-amino-4-oxo- or 2,4-dioxo-6-aminopyrimidine afforded the dehydrogenated
在每种情况下,将三个2,4-二取代的6-氨基嘧啶与1-苄基-4-氧代-3-哌啶甲酸甲酯缩合,可得到新的三环,有角的1,3,8-三取代的嘧啶[4,5- c ] [ 2,7]萘啶-6-一。2,4,6-三氨基嘧啶如所预期得到7,8,9,10-四氢环缩合产物5。然而,使用2-氨基-4-氧-或2,4-二氧-6-氨基嘧啶提供了脱氢的9,10-二氢三环产物11和12。1,3-二氨基类似物5在2×10 -6 M时和1,3-二氧代类似物12在10 -5 M时,使培养的白血病L1210细胞生长受到50%的抑制。
