摘要:The invention relates to intermediates useful in the preparation of halichondrin compounds, methods for preparing the same and use thereof, such as halichondrins, eribulin, or their analogs. The intermediates, the methods and use thereof are used for the synthesis of the C20-C26 fragment of halichondrin compounds. The raw materials in the synthetic route of the invention are cheap and easily obtained, the sources and the qualities of the raw materials are reliable. The choice of the methods useful in the synthesis of chiral central structures are based on the structural characteristics of the reactants, thus effectively improving the synthesis efficiency, reducing the difficulties and risks of product quality control, and avoiding the use of highly toxic and expensive organotin catalysts to significantly decrease costs and improve environmental friendliness.

标题 :Methods for the manufacturing of nanostructured metals, metal carbides, and metal alloys
发明人：GONSALVES KENNETH E; RANGARAJAN SRI PRAKASH

摘要:Methods for the manufacture of nanostructured metals, metal carbides, and metal alloys are presented, such metals including nanostructured aluminum, chromium, iron, molybdenum, vanadium, and steel. Preferably, the nanostructured steel is of the M50 type, and comprises iron, molybdenum, chromium, vanadium and carbon. Synthesis of M50 steel further comprising nanostructured aluminum, aluminum oxide, or aluminum nitride is also described. In accordance with an important feature of this invention, the grain size of the metals and metal alloys is in the nanometer range. In accordance with the method of the present invention, the nanostructured metals, metal carbides, and metal alloys are prepared via chemical synthesis from aluminum, iron, molybdenum, chromium and vanadium starting materials. Decomposition of metal precursors or co-precipitation or precipitation of metal precursors is followed by consolidation of the resulting nanostructured powders. Alternatively, nanostructured M50 steel may be obtained by mixing of nanocrystalline chromium, iron, molybdenum, and vanadium powders, followed by ball-milling, and consolidation. The nanostructured metals, metal carbides, and metal alloys of this invention find particular utility in the manufacture of cutting tools and bearings, and in ferrofluids, magnetic memory systems, and catalysis.

标题:Catalytic synthesis of delta-valerolactone (dvl) from furfural-derived 2-hydroxytetrahydropyran (hthp)

摘要:A method to make delta-valerolactone (“DVLâ€?) by dehydrogenating 2-hydroxytetrahydropyran (“HTHPâ€?). The HTHP is contacted with a supported-metal catalyst for a time, at a temperature, and at a pressure wherein at least a portion of the HTHP is converted to DVL via dehydrogenation of the HTHP. The HTHP may be derived from biomass. Thus, the method yields DVL without requiring a petroleum-based feedstock.
