摘要:The present invention provides an efficient and versatile method for the synthesis and screening of combinatorial libraries of benzimidazoles, benzoxazoles, benzothiazoles, and derivatives thereof. In order to expedite the synthesis of large arrays of compounds possessing these core structures, a general methodology for solid phase synthesis of these derivatives is provided. Arrays of benzimidazoles, benzoxazoles, benzothiazoles, and derivatives thereof useful as peptidomimetics and for the identification of agents having antifungal, antiviral, antimicrobial, anticoagulant, and antiulcer activity, or use in the treatment of inflammation, hypertension, cancer, and other conditions can be prepared by this method.

标题 :Synthesis of (dibromocyclobuta) aromatic compounds
发明人：STANGER AMNON
权利人:TECHNION RES & DEV FOUNDATION
摘要:A method for the synthesis of cyclobuta aromatic compounds by cyclizing two ortho dibromoalkyl substituents is described. Using a mediator, such as nickel metal, and continuous removal of product from contact with the mediator, high product yields are achieved. A method for bromination of ortho alkyl substituents of aromatic compounds is also described.

摘要:The present invention relates to a new type of inorganic coordination compound dyes having advanced technology optical, electronic and medical characteristics and relates to production of these dyes by means of new synthesis methods. The present invention relates to dyes which are metal (M: Li, Na, K, Mg, Ca, Sr, Ba, Ti, Zr, V, Cr, Mo, Mn, Re, Fe, Ru, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, B, Al, Ga, In, Si, Ge, Sn, Pb, Sb, Bi, Se, Te) complexes of aromatic macrocyclic compounds of the type Phtalocyanine (Pc), Naphtalocyanine (Nc), Porphyrazine (Pz), Porphyrin (Pr), sub-Phtalocyanine (subPc), sub-Naphtalocyanine (subNc), sub-Porphyrazine (subPz), sub-Porphyrine (subPr), and relates to the synthesis of these complexes and derivatives. The subject matter dyes can be used in solar cell photovoltaic (PV) panels, in OLEDS which are organic structured light emitting diodes, in polymers, in textile and in photodynamic therapy PDT applications. Moreover, industrial applications are possible which depend on strong fluorescence characteristics.
