标题 :Solid phase and combinatorial synthesis of substituted thiophenes and of arrays of substituted thiophenes

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:The present invention is directed to compositions and methods for enhancing synthesis of nucleic acid molecules, particularly GC-rich nucleic acid molecules. Specifically, the invention provides compositions comprising one or more nitrogen-containing organic compounds having a formula selected from the group consisting of formula I and formula II (or salts or derivatives thereof), preferably 4-methylmorpholine N-oxide or betaine (carboxymethyltrimethylammonium), and further comprising one or more compounds selected from the group consisting of proline and an N-alkylimidazole compound, and more preferably proline, 1-methylimidazole or 4-methylimidazole. The invention further relates to methods for enhanced, high-fidelity synthesis of nucleic acid molecules, including via amplification (particularly PCR), reverse transcription, and sequencing methods. The invention also relates to nucleic acid molecules synthesized by these methods, to fragments or derivatives thereof, and to vectors and host cells comprising such nucleic acid molecules, fragments, or derivatives. The invention also relates to kits for synthesizing, amplifying, reverse transcribing or sequencing nucleic acid molecules comprising one or more of the compositions of the invention.

摘要:The present invention provides a highly efficient, versatile one-step process for asymmetric synthesis of either diastereomer of 2-substituted pyrrolidines from a single starting material with excellent yields and high diastereoselectivety. Also provided is a method for the asymmetric synthesis of both diastereomers of 2-substituted piperidines with good yields and excellent diastereoselectivety. Diasteroselectivity is controlled effectively by choice of reducing agent.

摘要:Nucleotide analogs that can sustain the enzymatic synthesis of double-stranded nucleic acid from a nucleic template are described. The nucleotide analogs include: (i) a base selected from the group consisting of adenine, guanine, cytosine, thymine, uracil and their analogs; (ii) a label attached to the base or analog of the base via a cleavable linker; (iii) a deoxyribose; and (iv) one or more phosphate groups. The linker and/or the label inhibits template directed polymerase incorporation of a further nucleotide substrate onto an extended primer strand. In addition, cleavage of the linker leaves a residue attached to the base which is not present in the natural nucleotide and which does not inhibit extension of the primer strand. The nucleotide analogs can therefore be used as reversible terminators in sequencing by synthesis methods without blocking the 3′ hydroxyl group. Methods of sequencing DNA using the substrates are also described.
