Simultaneous synthesis of thioesters and iron-sulfur clusters in water: two universal components of energy metabolism

Thioesters are important intermediates in both synthetic organic and biosynthetic reaction pathways. Here we show that thioesters can be synthesized in an aqueous reaction between thioacetate and thiols. The reaction can be coupled to a second reaction between sulfide and either ferrous or ferric iron, which drives the reaction forward. We furthermore demonstrate that sulfide released during thioester formation can be used in the synthesis of peptide bound [Fe-S] clusters, which like thioesters, are ancient components of metabolism. Together our results reveal a primordial linkage between high-energy ester formation and redox chemistry.

Magnetic cobalt ferrite nanoparticles functionalized with citric acid as a green nanocatalyst for one-pot three-component sonochemical synthesis of substituted 3-pyrrolin-2-ones

A clean, convenient and facile approach for one-pot ultrasonic assisted synthesis of substituted 3-pyrrolin-2-ones from diethyl acetylenedicarboxylate, aniline and aldehyde derivatives is described. The reactions were carried out in the presence of an efficient, green and reusable acidic nanocatalyst, magnetic cobalt ferrite nanoparticles functionalized with citric acid (CoFe2O4@CA), with high yields under mild conditions. Also, use of ultrasound irradiation made this approach an attractive protocol for the synthesis of these products. The method has been successful in achieving the green chemistry objective. An energy efficient protocol using ultrasound irradiation instead of conventional heating or stirring and use of ethanol as a non-hazardous, inexpensive and green solvent in the one-step reaction against sequential reaction steps thus combining the features of both economic and environmental advantages.

SYNTHESIS OF NITROXIDE CONTAINING POLYENES – 2 CHEMICALLY-MODIFIED RETINALS AND THEIR INTERACTION WITH BACTERIORHODOPSIN

The synthesis and spectroscopic characterization of two retinal analogues is described, the paramagnetic 3-pyrrolin-1-yloxy analogue 1 and its diamagnetic equivalent, the 3-pyrroline analogue 2. Various aspects of the synthesis of the aminoxy group containing polyenes are discussed. Upon interaction with bacterioopsin, both 1 and 2 are incorporated in the protein and form a system with lambda(max) 459 nm. Neither of the two bacteriorhodopsin analogues is photoactive. ESR spectroscopy data of the system containing 1 show that the ring part of the chromophore in the protein is rigidly fixed in orientation.

Thiol-functionalized PIM-1 for removal and sensing for mercury (II)

Polymers of intrinsic microporosity (PIMs) are a class of microporous polymers with rigid and contorted molecular structures. The special structures lead to incomplete space occupation, and the pores of PIMs originate from the formed void. In this work, we made attempts to expand the applications of PIMs to the aspect of heavy metal removal. First, PIM-1 was synthesized using tetrafluoroterephthalonitrile (TFTPN) and 5,5′,6,6′-tetrahydroxy-3,3,3′,3′-tetramethyl-1,1′-spirobisindane (TTSBI) as precursors. The primary PIM-1 was quite hydrophobic, and thus could not be evenly dispersed in water, resulting in low adsorption capacity for mercury ions (Hg2+). A conversion of nitrile group in PIM-1 to thiol group was then carried out by two steps, namely carboxylation and introduction of thiol groups. The carboxylation made the polymers more active, and the final thiol-functionalization provided the polymers with hydrophilicity and affinity for Hg2+. The thiolethyl modified PIM-1 (assigned as PIM-G) and thiophenyl modified (assigned as PIM-B) possessed maximum Hg2+ adsorption capacity of 136 mg g(-1) and 127 mg g(-1) at pH 5, respectively. Besides, the thiol-functionalized PIMs had fluorescence property and showed potential in sensing for Hg2+.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 1977-07-7, you can contact me at any time and look forward to more communication. Recommanded Product: 1977-07-7.
