Facile synthesis of 5-bromotropono[${c}$]-fused pyrazoles and isoxazole

Abstract

(17) is described, involving a condensation reaction of 3-acetyl-5-bromotropolone (1) with hydrazine monohydrate (2), arylhydrazine hydrochlorides (4-9), and hydroxylamine hydrochloride (16), respectively.All the synthesized compounds were obtained in good yields of 56%-77% and their structures were characterized by spectral data and HRMS.

A Novel Synthesis of 2‐Ferrocenoyl‐Substituted Iodobenzofurans

“…To the best of our knowledge, the construction of this type of hybrid molecules still remained unknown. Accordingly, with this context and in continuation of our studies on the synthesis of highly interesting types of hybrid heterocycles [14][15][16][17][18][19], we would like to report, herein, the first synthesis of a series of meaningful 2-ferrocenoyl-based iodobenzofurans.…”
