Regiochemistry Discoveries in the Use of Isoxazole as a Handle for the Rapid Construction of an All-Carbon Macrocyclic Precursor in the Synthetic Studies of Celastrol

We have developed a convergent synthetic route to an all-carbon, 14-membered Z,E-macrocyclic bis-enone during our synthetic study of celastrol. The 1,3-dipolar cycloaddition of nitrile oxide and alkyne was employed for fragment coupling and introducing the 1,3-diketone moiety masked in the form of an isoxazole. We discovered that cycloaddition of the nitrile oxide and the enyne gave the rare 3,4-disubstituted isoxazole adduct under kinetic reaction conditions The,cycloaddition was found to be reversible, and the thermodynamic 3,5-disubstituted isoxazole could be obtained by isomerization of its 3,4-disubstituted isomer under elevated temperature. Our mechanistic studies support the role of hydrogen bonding in accelerating the isomerization. Consistent with our previous studies, the Z,E-macrocyclic bis-enone was found to be inactive toward the transannular bis-Michael reaction under the conditions evaluated.

Efficient Synthesis and Properties of a Photochromic hybrid Diarylethene Bearing a Isoxazole Moiety

A novel photoehromic hybrid diarylethene based on both isoxazole and cyano moieties was synthesized and its photochromic and fluorescent properties were also investigated. This compound exhibited good photochromism and functioned as a fluorescence switch upon alternating irradiation with UV and visible light both in solution and in PMMA film. Using this diarylethene 1c as optical storage was performed successfully.

Microwave accelerated synthesis of isoxazole hydrazide inhibitors of the system x(c-) transporter: Initial homology model

Microwave accelerated reaction system (MARS) technology provided a good method to obtain selective and open isoxazole ligands that bind to and inhibit the Sx(c-) antiporter. The MARS provided numerous advantages, including: shorter time, better yield and higher purity of the product. Of the newly synthesized series of isoxazoles the salicyl hydrazide 6 exhibited the highest level of inhibitory activity in the transport assay. A homology model has been developed to summarize the SAR results to date, and provide a working hypothesis for future studies. (C) 2013 Elsevier Ltd. All rights reserved.

Liquid crystals containing the isoxazole and tetrazole heterocycles

The influence of the bridging group between the mesogenic group and the terminal position on liquid-crystalline behavior was investigated. Two liquid-crystalline series containing pentagonal heterocycles were synthesized for this purpose. The liquid-crystal phase of mesogens with the isoxazole group was more stable than that of those with isoxazole and tetrazole groups in the same molecule. The mesogens with only the isoxazole group showed better thermal properties than those with isoxazoles and tetrazoles. Nematic and smectic phases were observed. The mesophase sequences of the materials were investigated by polarization microscopy and DSC (Differential Scanning Calorimetry).

Synthesis and Phototoxic Activity of Isoxazole and Pyrazoline Derivatives Containing alpha-Terthiophene

alpha-Terthiophene is a class of pesticides with predominant photoactivity. In this work, using terthiophene as the lead compound, the important mediator, 2-carbonyl terthiophene, was synthesized by the carbonylation. After reaction with substituted phenylethanone, terthiophene-substituted alpha,beta-unsaturated ketones were synthesized. Followed by the ring closure reaction with hydroxylamine hydrochloride and hydrazine, a series of 3,5-diaryl isoxazole and 3,5-diasyl pyrazoline drivatives containing alpha-terthiophene were synthesized, respectively. Their structures were confirmed by H-1 NMR, IR and elemental analysis. The biological activity assay indicated that most of the synthesized compounds exhibit strong photoactivities. In addition, the photoactivities of isoxazole derivatives were much better than those of pyrazoline derivatives, where the photoactivity difference of compound 3b was 64.06 before and after illumination, especially. However, some of the pyrazoline derivatives showed higher activities of killing cells, where the activity of the compound 4d was as high as 83.9%.
