标 题 :Method for the synthesis of pyrrole and imidazole carboxamides on a solid support
发明人：DERVAN PETER B; BAIRD ELDON
权利人:CALIFORNIA INST OF TECHN
摘要:The present invention describes a novel method for the solid phase synthesis of polyamides containing imidazole and pyrrole carboxamides. The polyamides are prepared on a solid support from aromatic carboxylic acids and aromatic amines with high stepwise coupling yields (>99%), providing milligram quantities of highly pure polyamides. The present invention also describes the synthesis of analogs of the natural products Netropsin and Distamycin A, two antiviral antibiotics. The present invention also describes a novel method for the solid phase synthesis of imidazole and pyrrole carboxamide polyamide-oligonucleotide conjugates. This methodology will greatly increase both the complexity and quantity of minor-groove binding polyamides and minor-groove binding polyamide-oligonucleotide conjugates which can be synthesized and tested.

摘要:The invention relates to a process for performing a aqueous synthesis of titanium phosphates (TiP) having solely —H2PO4 groups, which process is characterised by the following steps: providing titanium (IV) oxysulphate, TiOSO4, in an aqueous solution or in a powder and H2SO4, substantially without transition divalent metal ions, including cobalt (II) and copper (II), heating of the thus formed aqueous solution to above 50° C., but below 85° C. for at least 30 minutes, providing a controlled amount of H3PO4 to said aqueous solution, to form an aqueous solution containing a molar ratio between TIO2 and P2Os being controlled to about 1:1, not above 1:1.5 and not below 1:0.7, stirring the thus formed aqueous solution for at least 3 hours to form precipitates of titanium phosphate, and allowing ageing of said solution, without stirring, acidic washing of the formed precipitate using HCI or other acids to obtain TiO(OH)(H2PO4)-H2O having solely —H2PO4 ion-exchange chemical groups and allowing said precipitates to dry to a powder product, substituting protons in the powder product TiO(OH)(H2PO4)-H2O to sodium cations by treatment of the latter with solutions of sodium carbonate and allowing the thus formed powder of Na—TiP1 to dry.

摘要:Described is a method of synthesizing a plurality of compounds in a plurality of wells comprising the steps of: (a) providing a plurality of test wells in a plurality of arrays of the wells; (b) reacting in at least a one step reaction a first reagent with a plurality of reagents called building blocks in the test well to obtain a unique product designed to be the same in each array; and (c) continuing to react reagents such that there are multiple reagents resulting in mixtures of multiple different products in each well.

标 题 :Synthesis of a Novel Ordered Mesoporous Carbon Using COK-19 Template for Water and Wastewater Treatment

摘要:Ordered mesoporous carbon was prepared using COK-19 silica template. Ordered mesoporous silica COK-19 was synthesized with cubic Fm3m structure. Sucrose as the carbon precursor was impregnated into the mesopores of silica and converted to carbon through carbonization process using sulfuric acid as a catalyst. Ordered mesoporous carbon was obtained after the removal of silica framework using hydrofluoric acid. Several characterization techniques such as nitrogen adsorption-desorption isotherms, transmission electron microscope (TEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and elemental analysis were employed to characterize the OMC. The pore size analysis and TEM images confirmed that OMC has replicated the mesostructure of the COK-19. Results obtained from adsorption kinetics and isotherms suggest that the Pseudo-Second-Order Model and Langmuir Isotherm well described the experimental data. The adsorption study showed that the synthesized OMC has an adsorption capacity of 40.5 mg/g for resorcinol removal.
