چکیده

A facile procedure is described for the preparation of [ "C]epicholesterol from [ '*C]cholesteroL Cholesterol is first converted to cholesteryl mesylate, which is treated with cesium acetate and 18-crown-6 in refluxing toluene to give epicholesteryl acetate. The latter is hydrolyzed, without isolation, with potassium hydroxide in tetrahydrofuran-methanol to give epicholesterol, which is obtained in pure form by preparative thin-layer chromatography. -Yan, J., and R.

A Facile and Efficient Synthesis of Tetrahydrobenzo[b]pyrans Using Sucrose as Green, Inexpensive, Natural and Biodegradable Catalyst

     A very efficient one-pot three-component synthesis of pyran derivatives has been improved by condensation of aldehydes and malononitrile with dimedone under 80 °C using sucrose as natural and biodegradable catalyst in water. This method offers some advantages including inexpensive, high to quantitative yields, short reaction time, and easy work-up. Therefore, this methodology is entirely g...

Synthesis of CuFeS2 Nanoparticles by One-pot Facile Method

Monodisperse copper-iron-sulfide (CuFeS2) nanoparticles as the infrared light absorbing material (chalcopyrite, 0.65 eV), were synthesized based on facile, one step heating up method, by dissolving of CuCl, FeCl3 and SC(NH2)2 as precursors in oleylamine (OLA) alone or in combination with oleic acid (OA) and 1-octadecene (ODE) as solvent. The phase, size, morphology, and size distribution were c...
