Lactones of Hydrogenated 5,8-Dihydroxy-4-methylnaphthalene-1-carboxylic Acids

Toxicological Profile for Naphthalene, 1-methylnaphthalene, and 2-methylnaphthalene

Direct conversion of esters, lactones, and carboxylic acids to oxazolines catalyzed by a tetranuclear zinc cluster.

The tetranuclear zinc cluster Zn4(OCOCF3)6O catalyzes the direct conversion of esters, lactones, and carboxylic acids to oxazolines with remarkable chemoselectivity.

Toxicological Profile for Naphthalene, 1-methylnaphthalene, and 2-methylnaphthalene

The antimutagenicity of 2-substituted selenazolidine-4-(R)-carboxylic acids.

Selenium can have cancer chemopreventive activity, although the mechanism of action has not been well defined. Selenazolidine-4-(R)-carboxylic acids (SCAs) were devised as prodrugs of L-selenocysteine, to provide selenium in a form and at a concentration commensurate with cancer chemopreventive activity. In the present study, a series of selenazolidines has been evaluated in the Salmonella typh...

Fe3O4@ZrO2-SO3H Nano-particles for esterification of carboxylic acids

In this work preparation of sulfonic acid functionalized magnetite encapsulated zirconia (Fe3O4@ZrO2-SO3H) has been reported. Structural, chemical, and magnetic properties of the magnetically supported catalyst have also been investigated by Fourier transform infrared (FT-IR) spectroscopy, wide angle X-ray diffraction spectroscopy (WXRD), thermal gravimetric analysis (TGA), energy dispersive X-...
