摘要:A process is described for the preparation of the core azobicyclo[7.3.1]tridecaenediyne moiety of the antitumor antibiotic dynemicin. The synthesis allows efficient production of the enediyne as a stable, compound in good yield from the adamantyl N-protected azabicyclo[7.3.1]tridecadiyne. The adamantyl protecting group is employed in the starting material, N-adamantyl dihydroquinoline or N-adamantyl 6-methoxy quinoline. Also disclosed are process for the synthesis of 3-hydroxy-6-methoxyquinoline and several N-substituted derivatives of azobicyclo[7.3.1]tridecaenediyne. Solid tumor and leukemia assays were performed on the analogs of dynemicin. The results suggest a method that these compounds will useful in treating certain types of leukemias and solid tumors. The disclosed synthesis provides a route to new dynemicin intermediates and analogs which will allow development of second and third generation dynemicins.

标 题 :Template-assisted synthesis of 2D nanosheets using nanoparticle templates
发明人：DANIELS STEVEN; PICKETT NIGEL L
权利人:NANOCO TECHNOLOGIES LTD; NANOCO 2D MAT LIMITED
摘要:A template-assisted method for the synthesis of 2D nanosheets comprises growing a 2D material on the surface of a nanoparticle substrate that acts as a template for nanosheet growth. The 2D nanosheets may then be released from the template surface, e.g. via chemical intercalation and exfoliation, purified, and the templates may be reused.

标题:Chemical Synthesis Method for Pseudomonas aeruginosa Serotype O5 O-Antigen Oligosaccharide
发明人：YIN JIAN; HU JING; TIAN GUANGZONG
权利人:UNIV JIANGNAN
摘要:Disclosed is a chemical synthesis method for Pseudomonas aeruginosa O5 serotype O-antigen oligosaccharide, which belongs to the field of chemical synthesis. In the disclosure, O-antigen trisaccharide is constructed with a D-glucuronic acid building block and a D-fucosamine building block, where the stereoselective synthesis of a 1,2-α-cis-glycosidic bond of D-fucosamine depends on remote acyl participation and reagent regulation, and synthesis of two types of 1,2-β-trans-glycosidic bonds of 2,3-diaminomannuronic acids is achieved via S N 2 nucleophilic substitution of azido at position C2; and via selective assembly of protecting groups, orthogonal modification of modifying groups, and regulation of the reactivity of glycosyl donors and acceptors, multifunctional modified O-antigen target trisaccharide is successfully prepared. According to the method in the disclosure, the raw materials are cheap and easily available, and the preparation method is simple and easy to repeat. Therefore, the method has a very good application prospect in developing vaccines against P. aeruginosa.

标 题:One-pot synthesis of high-quality metal chalcogenide nanocrystals without precursor injection
发明人：CAO YUNWEI CHARLES
权利人:UNIV FLORIDA
摘要:A method of homogeneously forming metal chalcogenide nanocrystals includes the steps combining a metal source, a chalcogenide source, and at least one solvent at a first temperature to form a liquid comprising assembly, and heating the assembly at a sufficient temperature to initiate nucleation to form a plurality of metal chalcogenide nanocrystals. The plurality of metal chalcogenide nanocrystals are then grown without injection of either the metal source or the chalcogenide source at a temperature at least equal to the sufficient temperature, wherein growth proceeds substantially without nucleation to form a plurality of monodisperse metal chalcogenide nanocrystals. An optional nucleation initiator can help control the final size of the monodisperse crystals. Such synthesis, without the need for precursor injection, is suitable for the industrial preparation of high-quality nanocrystals.
