标 题 :Process for the synthesis of 2′-O-substituted purine nulceosides
发明人:RAVIKUMAR VASULINGA
权利人:ISIS PHARMACEUTICALS INC
摘要:The present invention provides an improved process for the synthesis of 2′-O-substituted purine nucleosides. The process includes anhydro or thioanhydro ring opening of a selected 8,2′-cyclopurine nucleoside with a weak nucleophile in the presence of a Lewis acid ester, followed by reduction to afford the desired 2′-O-substituted purine nucleoside.

标 题:Bottom-Up, Scalable Synthesis Of Oxide-Based Sub-Nano And Nanofilaments And Nanofilament-Based Two-Dimensional Flakes And Mesoporous Powders
发明人:BARSOUM MICHEL W; BADR HUSSEIN OSAMA
权利人:UNIV DREXEL
摘要:Provided are methods to convert—through a bottom-up approach—binary and ternary titanium carbides, nitrides, borides, phosphides, aluminides, and silicides into lepidocrocitic nanofilaments that in some cases self-assemble into 2D flakes by immersing them in a quaternary ammonium solution at moderate temperatures. The resulting flakes can comprise nanofilaments in cross-section, some of which nanofilaments can be few microns long in some instances.

摘要:Provided are methods to convert - through a bottom-up approach – binary and ternary titanium carbides, nitrides, borides, phosphides, aluminides, and silicides into nanofilaments that in some cases self-assemble into 2D flakes by immersing them in a quaternary ammonium solution at moderate temperatures. The resulting flakes can be C-containing anatase-based layers that are in turn comprised of nanofilaments in cross-section, some of which nanofilaments can be few microns long in some instances. Electrodes made from these materials performed well in energy systems. The materials also reduce the viability of some cancer cells. Also provided are mesoporous materials, devices, and related methods.
