Reactions of 6-aminopyrimidines with 2-dimethylaminomethylenetetralone. Regiospecific Synthesis Of 5,6-Dihydrobenzo [<i>h</i>]pyrimido [4,5-<i>b</i>] quinolines
Benzo[h]pyrimido[4,5-b]quinolines (3) have been synthesized via a regiospecific cyclocondensation reaction between 6-aminopyrimidines (1) and 2-dimethylaminomethylentetralone hydrochloride (2). The linear structure of the final compounds were determined by nmr measurements, especially by 1H,1H, 1H,13C COSY and DEPT experiments.
苯并[ h ]嘧啶基[4,5- b ]喹啉(3)是通过6-氨基嘧啶(1)和2-二甲基氨基甲基四氢萘酮盐酸盐(2)之间的区域特异性环缩合反应合成的。最终化合物的线性结构通过nmr测量确定,尤其是通过1 H,1 H,1 H,13 C COZY和DEPT实验确定。

Novel tetracyclic compounds 1–4 have been synthesized via a regiospecific cyclocondensation reaction between substituted 6-aminopyrimidines 5–7 and chlorovinyl aldehydes 13 and 14. The linear structures of these compounds were established by 1H nmr and 13C nmr spectral data and also by synthesis of the compounds via an unambiguous route. The growth of Manca human lymphoma cells was inhibited 50% by
新颖四环化合物1-4已经合成了通过取代的6-氨基嘧啶之间的区域专一性缩合反应5- 7和氯乙烯基醛13和14。这些化合物的线性结构通过1 H nmr和13 C nmr光谱数据以及通过明确的途径合成化合物来建立。在4.5×10 -6 M和1.2×10 -6 M时,Manca人淋巴瘤细胞的生长被1和4抑制了50%。 分别。这些化合物也抑制人二氢叶酸还原酶(DHFR)的50%在4.4×10 -6 中号和1.4×10 -6无关和干酪乳杆菌的DHFR在1.9×10 -5 中号和1.1×10 -5 中号分别。化合物16是1的位置异构体,是所研究化合物中最有效的化合物,它在9×10 -8 M时可抑制Manca人淋巴瘤细胞的生长50%。抑制人DHFR和干酪乳杆菌DHFR的IC 50值为16,分别为8×10 -8 M和1.9×10 -5 M 分别。
