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。
