4-disubstituted 6-aminopyrimidines with 2-chloro-1-cyclohexenecarboxaldehyde afforded in each case a new regiospecific synthesis of tricyclic, linear disubstituted 6,7,8,9-tetrahydro-pyrimido[4,5-b]quinolines 2 and 3 in excellent yields. The linear structures and hence the regiospecificity of the synthesis were established using 1H nmr and 13C nmr. The growth of leukemia L1210 cells in culture was inhibited 50%
在每种情况下,两个2,4-二取代的6-氨基嘧啶与2-氯-1-环己烯甲醛的环缩合反应提供了一种新的区域特异性合成的三环,线性二取代的6,7,8,9-四氢-嘧啶[4,5- b ]喹啉2和3具有优异的收率。使用1 H nmr和13 C nmr建立了线性结构,从而确定了合成的区域特异性。白血病L1210细胞在培养中的生长在30×10 -6 M时被2抑制了50%,在100×10 -6 M时被3抑制了48%。
