标题 :Chemical synthesis of squalamine
发明人：MORIARTY ROBERT M; GUO LIANG; TULADHAR SUDERSAN M
权利人:MAGAININ PHARMA
摘要:Methods for the chemical preparation or synthesis of the sterol antibiotic squalamine. Preferably, the preparation is by modifying the 3-position of a 3-oxo-7α-hydroxy-24z-ether protected alcohol group-5α-cholestane with a spermidino moiety to form a 3β-spermidino-7α-hydroxy-24z-ether protected group -5α-cholestane; deprotecting the 24-position of the 3β-spermidino-7α-hydroxy-24z-ether protected group-5α-cholestane to the free hydroxyl; and sulfating the 24-position of the 3β-spermidino-7α, 24-dihydroxy-5α-cholestane.

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:Stereoselective synthesis of 24-hydroxylated compounds useful for the preparation of aminosterols, vitamin D analogs, and other compounds
发明人：KINNEY WILLIAM A; JONES STEVEN; ZHANG XUEHAI; RAO MEENA N; BULLIARD MICHEL; MECKLER HAROLD; LEE NANCY
摘要:A method is described for stereoselectively reducing an unsaturated alkyl ketone substituent attached to a fused ring base. In this method, the unsaturated alkyl ketone reacts with a chiral oxazaborolidine reagent. This reaction stereoselectively reduces the unsaturated alkyl ketone to an unsaturated alkyl alcohol. The unsaturated alkyl alcohol can be further reduced, if desired, to produce a saturated alkyl alcohol. The fused ring base can be, for example, a steroid ring base or a base of a vitamin D analog. The process in accordance with the invention can be used with an alkeneone substituent (e.g., a 22-ene-24-one substituent) or an alkyneone substituent (e.g., a 22-yne-24-one substituent) on a steroid ring base to make squalamine or other useful aminosterol compounds and intermediates for making aminosterol compounds.

标题:Synthesis of quinones and phenols on solid support
发明人：MARTINEZ LUIS E
权利人:UNIV TEXAS
摘要:Generally, and in one form, the present invention is a method of making a benzene-modified compound on solid support that includes the steps of forming an (oxy)(aryl)carbene complex, esterifying the (oxy)(aryl)carbene complex to form an (ester)(aryl)carbene complex, and contacting the (ester)(aryl)carbene complex with a solid support such that the (ester)(aryl)carbene complex is bound to the solid support. In another form, the present invention includes compositions for the resulting (ester)(aryl)carbene complexes on solid support, such as any resulting solid support compounds formed after the initial coupling as well as those from any subsequent reaction, including those with linkers and on a solid support. The method and compositions of the present invention yield stable, durable, highly efficient and cost-effective as well as potentially biologically active lead compounds on solid support.
