The synthesis of the unknown title Compounds is described. The preparation involves intramolecular acylation of 3-[1-phenyl-5-(1-pyrryl)pyrazol-4-yl]propanoic acid 9 to the tricyclic ketone 10, which was then transformed into 1H,4H-pyrazolo[4,3-f]pyrrolo[1,2-a]azepine 12 and its dihydro derivative 13 by reductive procedures.
描述了未知标题化合物的合成。制备过程涉及将3- [1-苯基-5-(1-吡咯基)吡唑-4-基]丙酸9分子内酰化为三环酮10,然后将其转化为1 H,4 H-吡唑并[4, 3- f ]吡咯并[1,2- a ]氮杂12和其二氢衍生物13通过还原程序。
