Highly enantioselective radical addition to N-benzoyl hydrazones using chiral ammonium salts

In the presence of a protonated cinchonine derivative, radical addition reactions proceeded efficiently, affording addition adducts in high yields with an extremely high enantioselectivity. The chiral ammonium salt was recyclable after a simple aqueous workup. The reaction provides environmentally benign reaction conditions. Copyright

Synthesis and biological evaluation in vitro and in silico of N-propionyl-N′-benzeneacylhydrazone derivatives as cruzain inhibitors of Trypanosoma cruzi

Abstract: An N-acylhydrazone scaffold has been used to develop new drugs with diverse biological activities, including trypanocidal activity against different strains of Trypanosoma cruzi. However, their mechanism of action is not clear, although in T. cr

Aniline Catalysed Hydrazone Formation Reactions Show a Large Variation in Reaction Rates and Catalytic Effects

Hydrazone formation reactions from aldehydes and hydrazides have the remarkable qualities that they proceed in water and the kinetics can be controlled by organocatalysis. For these reasons, this class of reactions finds widespread use in biological as well as material settings. We recently reported a protected aniline catalyst for hydrazone formation that can be activated using a chemical signal. In our search to find a suitable hydrazone formation reaction to investigate the activation of this pro-catalyst, we found a wide variety in reaction rates and response to catalysis. Here we report an overview of hydrazone formation reactions, their reaction rates and response to aniline catalysis, their compatibility for kinetic analysis by UV/Vis spectroscopy, and their compatibility with the reaction environment and with the pro-catalyst pro-aniline. (Figure presented.).

Selectively catalytic epoxidation of α-pinene with dry air over the composite catalysts of Co-MOR(L) with Schiff-base ligands

Twelve bi-/tridentate Schiff-base ligands (L1-L12) have been designed, synthesized and coordinated with ion-exchanged Co-MOR (Mordenite) forming a series of Co-MOR(L) composite catalysts, for which various analyzes and characterizations are conducted. Selectively catalytic epoxidation of α-pinene with dry air over Co-MOR(L) catalysts has been carried out, where uses TBHP in small amounts as the initiator. Among these Co-MOR(L) catalysts, Co-MOR(L8) exhibits the best activity for the titled reaction to obtain 85.8 mol% conversion and 90.8% selectivity of epoxide. Some factors such as the structure of ligands, the oxidants, the solvents, the catalyst amount, the reaction temperature and time play important roles in controlling the epoxidation. The recyclable stability of the Co-MOR(L8) catalyst is confirmed. The studies on the electrochemical behaviors of Co species in Co-MOR(L8) reveal the importance of reversible change between Co oxidation states for the epoxidation.

Solvent-free mechanochemical route for green synthesis of pharmaceutically attractive phenolhydrazones

A series of hydrazones, as potential therapeutic agents, were successfully synthesized in a vibratory ball-mill from various substituted organic hydrazines and phenol aldehydes. The degree of conversion was increased by high electronic density on the amino group of the hydrazine reactant, as well as low steric hindrance around both reactive sites. In this particular case, the flexibility of the chain bearing the amino reactive site of hydrazine was highlighted as a factor influencing the reaction rate. The results showed that hydrazones could be obtained with more than a 99% transformation, without concurring by-products. This is highly adapted to the synthesis of active pharmaceutical ingredients, requiring a high level of purity. Owing to the fact that neither an environmentally unadvisable reagent nor additives or catalysts were added to achieve the transformation, this synthesis provides a good example and a prefiguration of an efficient green pharmaceutical process.

Electrosynthesis and screening of novel 1,3,4-oxadiazoles as potent and selective antifungal agents

The electrochemical oxidation of aldehyde-N-aroylhydrazone has been studied in the presence of NaClO4 as supporting electrolyte in MeOH solution using cyclic voltammetry and controlled potential electrolysis. The results indicate that intramolecular cyclization of aldehyde-N-aroylhydrazone has been successfully performed at a platinum electrode in an undivided cell with good yields of the corresponding 1,3,4-oxadiazoles at ambient conditions. The reaction products were characterized by spectroscopic methods and a mechanism was deduced from voltammetry studies. The antifungal activity of the synthesized compounds was evaluated on Fusarium oxysporum, Alternaria solani, Candida albicans and Aspergillus niger. The results revealed that all the synthesized compounds have significant antifungal activity against the tested fungi. Among the synthesized derivatives 7b, 7d, 7g, 7h, 7i, 7j and 7r were found to be the most effective antifungal compounds. The Royal Society of Chemistry 2013.
