Vacuum-ultraviolet photolysis of aqueous reaction systems

The photolysis of liquid H2O by vacuum-ultraviolet (VUV) photolysis, and in particular by the radiation emitted by Xe-excimer sources (172 nm) is reviewed, and the impact of the primary radicals (hydroxyl (HO), hydrogen (H) and hydroperoxyl (HO2)) on dissolved organic and inorganic substrates described. Mechanisms of oxidative and reductive reaction manifolds are reported, interpreted and developed, in particular for nitrogen containing substrates. At the present state of research, at least semi-quantitative predictions on primary reaction paths and rate effects can be made, and oversimplified qualitative interpretations belong definitely to the past. Nevertheless, the review demonstrates clearly the lack of data concerning the reactivity of radical species, generated by inorganic anion oxidation, and their interaction with organic compounds and with the radicals derived from them.

Palladium-catalysed direct heteroarylations of heteroaromatics using esters as blocking groups at c2 of bromofuran and bromothiophene derivatives: A one-step access to biheteroaryls

Methyl 5-bromo-2-furoate and ethyl 5-bromothiophene-2-carboxylate have been found to be useful alternative reagents to 2-halofurans and 2-halothiophenes for the palladium-catalysed direct arylation of heteroaromatics. As their C5 is blocked by ester groups, the use of these substrates prevents the formation of dimers or oligomers, and therefore allows the formation of biheteroaryls in high yields. A very wide variety of heteroaromatics can be coupled with these two reagents. Moreover, with methyl 5-bromo-2-furoate, sequential catalytic C5 arylation, decarboxylation, catalytic C2-arylation reactions allowed the synthesis of 2,5-diarylated furan derivatives.

Combinatorial libraries of substrate-bound cyclic organic compounds

The invention relates to libraries of cyclic organic compounds and method of producing and assaying such libraries. According to the invention, each cyclic organic compound is constructed from a starting material in the form of a solid surface derivatized with a starting resin. Compounds are reacted with the resin to add or to form a cyclic group. The reactions are preferable carried out using a split resin procedure so that different compounds can be reacted with a plurality of subamounts so as to increase the size of the library. For example, compounds are reacted with a solid support bound starting resin to obtain a compound which includes an aldehyde functional group wherein the aldehyde compound or compounds reacted with it have substituents which are varied such that a mixture of products is obtained. The invention further relates to methods of producing combinatorial libraries of cyclic organic compounds from substrate bound compounds by cleaving the compounds from the support after synthesizing is completed and to assaying libraries of such compounds.

Synthesis of nitrogen and oxygen based pyrazole derivatives and its antitubercular and antimicrobial activity

Background: Pyrazole, oxazole and pyrimidine are nitrogen containing heterocycles which possess very good binding efficiency with receptor or proteins. Due to this effect it can be work as antitubercular agents with active substituents. The objective of this paper is clubbed the heterocycles to enhance their antitubercular potency. Methods: The active substituted pyrazole aldehydes were synthesized by reaction of phenyl hydrazine with different acetophenone followed by Vilsmeier-Haack formylation reaction. The isoxazole and aminopyrimidines were prepared by condensation of various chalcones with hydroxyl amine hydrochloride and guanidine hydrochloride respectively. The structures of the newly synthesized compounds were characterized by1H-NMR, Mass, IR and elemental analysis data. All the newly synthesized compounds were screened for their antibacterial activity against Gram-positive S.pyogenus and Gram negative E.coli, Paeruginosa, S.aureus and antitubercular activity against mycobacterium tuberculosis H37Rv. Results: Oxygen containing substituent in aromatic ring or heterocycles as a substituent were enhancing the antitubercular activity as compared to the other substituents. Ethoxy group present as a substituent in aromatic ring shows minimum inhibition concentration as compared to others. Conclusion: X-ray crystallographic study enhances that E-isomer formed in case of chalcones. The electron withdrawing group such as fluorine and chlorine enhancing the activity of Isoxazole and Pyridine as compare to the chalcones. Electron donating group such as ethoxy is increase the potency of the compounds at para position.
