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 1 H ,4 H ‐pyrazolo[4,3‐ f ]pyrrolo[1,2‐ a ]azepine 12 and its dihydro derivative 13 by reductive procedures.
