Novel Indole-Isoxazole Hybrids: Synthesis and In Vitro Anti-Cholinesterase Activity

Background: This work reports synthesis and in vitro cholinesterase inhibitory activity of novel indole-isoxazole hybrids. Method: The synthetic procedure was started from different ethyl 5-arylisoxazole-3-carboxylate derivatives. Hydrolysis and reaction of the later compound with tryptamine afforded the desired products in good yields. Conclusion: Among the synthesized compounds, N-(2-(1H-indol-3-yl) ethyl)-5-(2-chlorophenyl) isoxazole-3-carboxamide (4b) showed the best anti-cholinesterase activity.

SYNTHESIS OF UNSYMMETRICALLY SUBSTITUTED ISOXAZOLES AS INTERMEDIATES FOR BENT-CORE MESOGENS

3,5-Disubstituted isoxazoles have been designed and synthesized to be used as central units for bent-core mesogens. The substituents at position 3 of the isoxazole ring are either hydroxymethyl or carboxyl, while alkenyl-terminated substituents have been inserted at position 5. A multi-step reaction sequence comprising the O-alkylation of 4-hydroxyacetophenone with the suitable alkenyl halide, the Claisen-type condensation with diethyl oxalate and the cyclization to isoxazole led to the isoxazole esters as key intermediates, which were subsequently reduced and hydrolyzed to the corresponding isoxazol-3-ylmethanols and isoxazole-3-carboxilic acids, respectively.

Synthesis of 3-Nitroisoxazoles via Copper Acetate-Mediated Reaction of Benzaldehydes with Nitromethane

A copper acetate-mediated reaction of benzaldehydes with nitromethane to synthesis of 3-nitroisoxazoles is reported. A variety of nitro-aryl-disubstituted isoxazole derivatives can be prepared in moderate to good yields with benign functional group tolerance. This protocol is successfully applied in gram-scale reaction. Preliminary mechanistic studies reveal that the aldehyde provided one carbon atom for the isoxazole ring, and nitromethane provided two carbon atoms and one nitrogen atom for the isoxazole ring. In this protocol, the C-O-N unit in the final isoxazole ring is formed from the rearrangement of nitromethane.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 82717-96-2, in my other articles.
