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. The thiophenes are prepared by reaction of a substrate-bound primary or secondary amine with a thiophosgene equivalent and reaction of the resulting intermediate with an acceptor-substituted acetonitrile in the presence of a base. Alkylation with an appropriate alkyl halide, followed by Thorpe-Ziegler-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:A solid phase method for the synthesis of a plurality of differently substituted 1,2,3-triazoles with a wide variety of side-chain substituents as compounds of potential therapeutic interest. The 1,2,3-triazoles are prepared by acylation of a substrate-bound primary or secondary amine with a 3-oxoalkanoic acid and reaction of the resulting amide with a primary amine under dehydrating conditions to give an enamine. Treatment of this substrate-bound enamine with a sulfonyl azide in the presence of a base gives the corresponding 1,2,3-triazoles. These may be screened on the substrate or cleaved from the substrate and then screened in solution. The efficient synthesis of a wide variety of 1,2,3-triazoles using automated synthesis technology of the present method makes these compounds attractive candidates for the generation and rapid screening of diverse triazole-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: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.

摘要:A solid phase method for the synthesis of a plurality of differently substituted 2-methylenethiazoles with a wide variety of side-chain substituents as compounds of potential therapeutic interest. The 2-methylenethiazoles 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 under acidic conditions yields differently substituted, support-bound 2-methylene-2,3-dihydrothiazoles. These may be screened on the substrate or cleaved from the substrate and then screened in solution. The efficient synthesis of a wide variety of 2-methylenethiazoles using automated synthesis technology of the present method makes these compounds attractive candidates for the generation and rapid screening of diverse thiazole-based libraries.

摘要:A solid-phase method for the synthesis of N-substituted oligomers, such as poly (N-substituted glycines) (referred to herein as poly NSGs) is used to obtain oligomers, such as poly NSGs of potential therapeutic interest which poly NSGs can have a wide variety of side-chain substituents. Each N-substituted glycine monomer is assembled from two 'sub-monomers' directly on the solid support. Each cycle of monomer addition consists of two steps: (1) acylation of a secondary amine bound to the support with an acylating agent comprising a leaving group capable of nucleophilic displacement by -NH2, such as a haloacetic acid, and (2) introduction of the side-chain by nucleophilic displacement of the leaving group, such as halogen (as a solid support-bound alpha -haloacetamide) with a sufficient amount of a second sub-monomer comprising an -NH2 group, such as a primary amine, alkoxyamine, semicarbazide, acyl hydrazide, carbazate or the like. Repetition of the two step cycle of acylation and displacement gives the desired oligomers. The efficient synthesis of a wide variety of oligomeric NSGs using automated synthesis technology of the present method makes these oligomers attractive candidates for the generation and rapid screening of diverse peptidomimetic libraries. The oligomers of the invention, such as N-substituted glycines (i.e. poly NSGs) disclosed here provide a new class of peptide-like compounds not found in nature, but which are synthetically accessible and have been shown to possess significant biological activity and proteolytic stability. Combinatorial libraries of cyclic compounds are disclosed wherein the cyclic compounds are comprised of at least one ring structure derived from cyclization of a peptoid backbone. The diversity of product compounds is generated by the sequential addition of substituted submonomers. The combinatorial library includes 10 or more, preferably 100 or more, and more preferably 1,000 or more distinct and different compounds. The library includes each of the product compounds in retrievable and analyzable amounts and preferably includes at least one biologically active compound. Methods of synthesizing the combinatorial libraries and assay devices produced using the libraries are disclosed as is methodology for screening for and obtaining biologically active cyclic organic compounds.

标 题 :Method for the synchronous absorption of carbon dioxide from flue gas and synthesis of dialkyl carbonates and alkylene carbonates

摘要:The invention relates to a synchronous CCU method (carbon dioxide capture and utilisation) for the absorption of carbon dioxide from flue gas and other CO 2 -containing substance sources and simultaneous synthesis of dialkyl carbonates and alkylene carbonates. The general subject matter of the invention is, in terms of a 'carbon dioxide capture' on the one hand, the absorption of CO 2 from flue gas and other CO 2 -containing substance sources with ammonia and/or amines to form ammonium carbamates or ammonium hydrogen carbonates or ureas or urea intermediates and, in terms of a 'carbon dioxide utilisation' on the other hand, the reaction of ammonium carbamates or ammonium hydrogen carbonates or ureas or urea intermediates with aliphatic, alicyclic or unsaturated alcohols, and including unsaturated aromatic alcohols to give dialkyl carbonates or alkylene carbonates in such a form that the CO 2 n absorption agent is re-released and fed back into the repetitive process again. A repetitive process control is extremely energy and CO 2 n efficient.
