Following our reports on synthetic tricyclic analogues of antitumor anthramycin the synthesis of some isomers pyrazolo[4,5-d]- and pyrazolo[4,5-c][1]benzazepinederivatives is reported.
继我们关于抗肿瘤蒽霉素的合成三环类似物的报道之后,报道了一些异构体吡唑并[4,5- d ]-和吡唑并[4,5- c ] [1]苯并ze庚因衍生物的合成。
Tricyclic heteroaromatic systems. 1,2,3,4-tetrahydropyrazolo[4,3-<i>c</i>][l]benzazepin-1-ones as potential antitumor agents
The synthesis of 1,2,3,4-tetrahydropyrazolo[4,3-c][1]benzazepin-1-ones 1 and that of its 10-methyl derivative 2 is reported. The preparation of the latter from 3-(2-aminobenzyl)3-pyrazolin-5-one and triethyl ortho-formate gave as the main product a derivative of the new tricyclic ringsystem, pyrazolo[1,5-c][1,3]benzo-diazepine. The structures of the new compounds synthesized were assigned by means
报道了1,2,3,4-四氢吡唑并[4,3- c ] [1]苯并ze庚因-1-酮1及其10-甲基衍生物2的合成。由3-(2-氨基苄基)3-吡唑啉-5-酮和原甲酸三乙酯制备后者,以新产物三唑环吡唑并[1,5- c ] [1, 3]苯并二氮杂.。通过13 C nmr研究确定了合成的新化合物的结构。
