标 题 :Solid phase and combinatorial synthesis of substituted thiophenes and of arrays of substituted thiophenes
发明人：DOERWALD FLORENCIO ZARAGOZA
权利人:NOVO NORDISK AS
摘要:A solid phase method for the synthesis of a plurality of differently substituted thiophenes with a wide variety of side-chain substituents as compounds of potential therapeutic interest is disclosed. The thiophenes are prepared by acylation of a substrate-bound primary or secondary amine with cyanoacetic acid and reaction of the resulting cyanoacetamide with an isothiocyanate in the presence of a base. Alkylation with an appropriate alkyl halide, followed by Thorpe-Ziegier-cyclization yields differently substituted, support-bound 3-aminothiophenes. These may be screened on the substrate or cleaved from the substrate and then screened in solution. Alternatively, the resin-bound 3-amino thiophenes or the synthetic intermediates can be subjected to further synthetic transformations (N-acylation, reduction) on the support, which permits the preparation of further therapeutically interesting compounds. The efficient synthesis of a wide variety of thiophenes using automated synthesis technology of the present method makes these compounds attractive candidates for the generation and rapid screening of diverse thiophene-based libraries. The method disclosed here provides an easy and fast access to highly diverse heterocyclic compounds of therapeutic interest, amenable to automatization.

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 :Process for the synthesis of torsemide, in particular of pure and stable form II
发明人：LUSSANA MASSIMILIANO; RAINONI MAURO; GAMBUZZA FILIPPO
权利人:COSMA S P A
摘要:The present invention relates to a new process for the synthesis of torsemide, in particular of pure and stable form II, which comprises direct synthesis of torsemide from 4-(3-methylphenylamino)-3-pyridine-sulphonamide. The new process envisages fewer steps than the processes described in the prior art, with improved yields and good quality from the chemical and preferably polymorphous points of view.
