Abstract:
2-heteroylhydrazonopropanals 2a–e and 3-oxo-2-arylhydrazonopropanals 2f–k were prepared via coupling of enaminones 1 with aromatic diazonium salts. Compounds 2a–c condensed with hydrazine hydrate to yield the corresponding hydrazones 3a–c which afford on cyclisation the cinnoline derivatives 6a–c, while condensation of 2g, j with hydrazine hydrate directly yielded the pyrazole derivatives 4g–j. Condensation of 2a–c, f, g with phenyl hydrazine gave the corresponding phenyl hydrazone derivatives 7a–c, f, g. Structures of 2a, h and 3a were assessed by single crystal X-ray analyses.

Abstract:
Vilsmeier-Haack reaction is one of the most important chemical reactions used for formylation of electron-rich arens. Even though Vilsmeier-Haack reaction was studied on a wide variety of hydrazones of enolizable ketones, literature lacks the examples of the use of 4-substituted cyclohexanones as a substrate. The cyclization potential of hydrazones of cyclic keto compounds is still interested topic of investigation. In the present study, the reaction of various hydrazines with 4-substituted cyclohexanones was proceeded and the resulted hydrazones in crude form were treated with Vilsmeier- Haac

Abstract:
The present study depicts the green synthesis of different Pyrazole derivatives from Phenyl hydrazones. The 1,3-dipolar cycloaddition reaction of Phenyl hydrazones with Benzoquinone is carried out under mild basic condition using bases like Pyridine and Triethyl amine. The reaction is conducted at room temperature so the unwanted by products are not formed. The work-up is also easy and can be accomplished by pouring the reaction mixture on ice and filtration of the solid product formed in the reaction. The crude products are further purified by the Column chromatography or recrystallisation te

The compounds elongated the nucleation phase and slowed down the tubulin polymerization comparably to nocodazole. The possible binding modes of the hydrazones with tubulin were explored by molecular docking at the colchicine binding site. The anticancer activity was evaluated against human malignant cell lines MCF-7 and AR-230, as well as against normal fibroblast cells 3T3 and CCL-1. The compounds demonstrated a marke
