chloride 14 were converted via Fischer syntheses with 3‐methylbutan‐2‐one into indolenines, 2,3,3‐trimethyl‐3H‐pyrrolo[2,3‐f]isoquinoline 15 and 5‐bromo‐2,3,3‐trimethyl‐3H‐pyrrolo[3,2‐h]isoquinoline 16, respectively. Exposure of the indolenines to the Vilsmeier reagent produced diformyl compounds 17 and 18, which reacted with arylhydrazines to give the corresponding pyrazoles 19a, 19b, 19c, 19d, 19e,
