Synthesis and characterization of a new series of liquid crystal compounds derived from isoxazoles

Two homologous series of phenylisoxazoles derived from 3-[4-(4-trans-n-heptylcyclohexyl)phenyl]-5-(4-alkoxyphenyl)isoxazole and 3-[4-(4-trans-n-heptylcyclohexyl)phenyl]-5-(5-nalkylthiophene)isoxazole have been synthesized. The liquid crystal compounds obtained were characterized by NMR, differential scanning calorimetry (DSC), and optical polarized microscopy (POM). The properties of the liquid crystalline phase were investigated as a function of terminal units and type of core aromatic rings. It was found that (1) the phase transition temperature decreased with the change of core aromatic rings from phenyl for thienyl, and (2) the types of mesophase formed by these compounds do not depend on the length of the terminal chain. Thermotropic nematic and smectic phases were observed.

Investigation of the scope of a [3+2] cycloaddition approach to isoxazole boronic esters

The [3 + 2] cycloaddition reaction of nitrile oxides and alkynylboronates provides direct access to a wide variety of isoxazole boronic esters. Specifically, this technique has been employed to generate trisubstituted isoxazole 4-boronates and disubstituted isoxazoles where the boronic ester moiety can be installed at C-4 or C-5 with high levels of regiocontrol. The application of this methodology in the synthesis of non-steroidal antiinflammatory agents is also described. (c) 2005 Elsevier Ltd. All rights reserved.

The synthetic and therapeutic expedition of isoxazole and its analogs

Isoxazole, constituting an important family of five-membered heterocycles with one oxygen atom and one nitrogen atom at adjacent positions is of immense importance because of its wide spectrum of biological activities and therapeutic potential. It is, therefore, of prime importance that the development of new synthetic strategies and designing of new isoxazole derivatives should be based on the most recent knowledge emerging from the latest research. This review is an endeavor to highlight the progress in the chemistry and biological activity of isoxazole derivatives which could provide a low-height flying bird’s eye view of isoxazole derivatives to the medicinal chemists for the development of clinically viable drugs using this information.

Two series of diaziridinyl quinone isoxazole derivatives were prepared and evaluated for their cytotoxic activity against MCF7, HeLa, BT549, A549 and HEK293 cell lines and interaction with tubulin. Compounds (6a-m) showed promising activity against all the 5 human cancer cell lines. Compounds 6a, 6e and 6 m were potent [IC50 ranging between 2.21 mu g to 2.87 mu g] on ER-positive MCF7 cell line similar to the commercially available drug molecule Doxorubicin. The results from docking models are in consistent with the experimental values which demonstrated the favourable binding modes of compounds 6a-m to the interface of a-and ss-tubulin dimer.

Harnessing the TEMPO-Catalyzed Aerobic Oxidation for Machetti-De Sarlo Reaction toward Sustainable Synthesis of Isoxazole Libraries

A practical synthesis of isoxazole/isoxazoline derivatives via Machetti-De Sarlo reaction under sustainable conditions has been accomplished. This protocol involves the use of readily available 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) to catalyze the cyclocondensation of primary nitroalkanes with alkynes/alkenes to afford a library of isoxazole/isoxazoline products. From an eco-benign perspective, notable advantages of this method are as follows: (i) water as the solvent, (ii) air as the oxidant, (iii) transition metal-free, (iv) no base required, (v) no toxic byproduct, (vi) no need of solvent extraction, (vii) diverse substrate scope, (viii) high chemical yields, (ix) excellent chemo- and regioselectivity, (x) short reaction time, (xi) gram-scale synthesis, (xii) extension to heterogeneous version, and (xiii) catalyst recyclability. For these reasons, the developed method is appropriate for safe laboratory use and can be expected to inspire the progress of TEMPO-based organocatalysis for the preparation of isoxazole/isoxazoline moieties in an environmentally benign fashion.

Reference of 199327-61-2, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 199327-61-2 is helpful to your research.

Methylation of compound (4a) afforded the two isomeric pyrazole derivatives (4b) and (5).

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 4432-31-9, in my other articles.
