Synthesis and characterization of selected fused isoxazole and pyrazole derivatives and their antimicrobial activity

New potent antibacterials, fused isoxazole and pyrazole derivatives, were synthesized using 5,5-dimethylcyclohexane-1,3-dione (1) and 3-[(4-chlorobenzylidene)amino]-2-thioxoimidazolidin-4-one (2) as synthons. Aromatic aldehydes on condensation with I and 2 gave 2-arylidene-5,5-dimethylcyclohexane-1,3-dione (3) and 5-arylidene-3-[(4-chlorobenzylidene)amino]-2-thioxoimidazolidin-4-one (4), respectively. Compounds 3 and 4 were forced to undergo heterocyclization reaction with nucleophilic reagents to give the title compounds. The newly synthesized heterocyles (5-8) were characterized based on their chemical properties and spectroscopic data, and were found to inhibit Staphylococcus aureus and Corynebacterium diphtheriae.

Simple primary amine catalyzed aerobic reductive ring-cleavage of isoxazole motif

A clean and highly efficient catalytic aerobic reductive ring-cleavage of 3-methylanthra[1,2-c]isoxazole-6,11-dione to 1-amino-2-acetylanthraquinone was performed using simple organic amines as organocatalysts and water as a green reaction medium. This method provides a new clean transformation of isoxazole-containing compounds to the corresponding ortho-amino ketones. The catalytic performance of various organic amines was carefully screened, and simple organic primary amines were found to be promising practical catalysts with outstanding catalytic performance. Isopropylamine as the organocatalyst gave 97.2% conversion of 3-methylanthra[1,2-c]isoxazole-6,11-dione, with 97.2% selectivity to 1-amino-2-acetylanthraquinone, in the presence of oxygen only, using 1 equiv. of hydrazine hydrate at room temperature for 3 h. A possible mechanism is also proposed. (C) 2015, Dalian Institute of Chemical Physics, Chinese Academy of Sciences. Published by Elsevier B.V. All rights reserved.

1,3-Dipolar cycloaddition reaction applied to synthesis of new unsymmetric liquid crystal compounds-based isoxazole

In this study, a regioselective, simple and versatile copper(I)-catalyzed procedure for preparation of a series of liquid crystals based on unsymmetrical 3,5-disubstituted isoxazole was developed. Using different substituted chloro oximes and phenyl acetylenes, 1,3-dipolar cycloaddition reaction was carried out. A second series containing the isoxazole ring and a triple bond in the rigid core was also synthesized. From the 3-(4-bromopheiiyl)-5-(4-(decyloxy)phenyl)isoxazole, new liquid-crystalline compounds were prepared by Sonogashira cross-coupling. All of the derivates of the isoxazole ring compounds exhibited mesomorphism. Smectic C, smectic A, and nematic phases were observed by optical microscopy and DSC analysis. The yield of these reactions varied from moderate to excellent (47-93%). The structure of the rigid core was investigated by single crystal X-ray diffraction, which confirmed the regioselectivity of the [3+2] dipolar cycloaddition reaction. (C) 2008 Elsevier Ltd.
