The synthesis of 4-(3,3-dimethyl-3H-pyrrolo[2,3-f]quinolin-2-yl)pyrazoles and 4-(3,3-dimethyl-3H-pyrrolo[3,2-h]quinolin-2-yl)pyrazoles by A. Rashidi; A. Afghan; Mehdi M. Baradarani; John A. Joule is a Chemistry article available to read on EtoBox.

What is The synthesis of 4-(3,3-dimethyl-3H-pyrrolo[2,3-f]quinolin-2-yl)pyrazoles and 4-(3,3-dimethyl-3H-pyrrolo[3,2-h]quinolin-2-yl)pyrazoles about?

## Abstract magnified image 5‐Hydrazinoquinoline and 8‐hydrazinoquinoline were converted __via__ Fischer syntheses with 3‐methyl‐butan‐2‐one into pyrido‐indolenines 2,3,3‐trimethyl‐3__H__‐pyrrolo[2,3‐__f__]quinoline **7** and 2,3,3‐trimethyl‐3__H__‐pyrrolo[3,2‐__h__]quinoline **11**, respectively. Exposure of the indolenines to the Vilsmeier reagent produced aminomethylene‐malondialdehydes **8** and **12**, which reacted with hydrazine or arylhydrazines to give 4‐(3__H__‐pyrrolo[2,3‐__f__]quinolin‐2‐yl)‐ and 4‐(3__H__‐pyrrolo[3,2‐__h__]quinolin‐2‐yl)‐pyrazoles, **9** and **13**.
