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 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:The present invention refers to the synthesis and intermediates of substituted bicyclic compounds by using a central 1H-pyrazolo[3,4-d]pyrimidine of formula (I), which is assembled starting from 4,6-dichloropyrimidine carboxylic acid. The invention in particular refers to the synthesis of the Bruton's tyrosine kinase (Btk) inhibitor 1-((R)-3-(4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)piperidin-1-yl)prop-2-en-1-one(ibrutinib) and its synthesis intermediates.
