摘要:A process for the chemical synthesis of oligonucleotides n Use of a dansylethoxycarbonyl group as base-labile 5'-hydroxyl protective group in the chemical synthesis of DNA and RNA and suitable synthetic processes. n The ease of detection of the dansyl protective group and the ease of elimination from the sugar residue of the nucleotide without side reactions make oligonucleotide synthesis possible with high yields in very small quantities.

摘要:Deoxyribonucleotide and ribonucleotide derivatives of the general formula I I wherein R1 represents -CR'R''-Ar, in which Ar is substituted aryl (as hereinafter defined) and R' and R'' are independently selected from the group consisting of hydrogen and lower alkyl; one of -R2 and R3 is a hydroxyl-protecting group and the other is a group suitable for synthesis of polynucleotides or for attachment of the nucleotide to a solid support; R4 is selected from the group consisting of hydrogen, -OH and protected hydroxyl; and B represents a divalent radical corresponding to a purine or pyrimidine base. When synthesis is carried out using these derivatives, the deprotection procedure is reduced to an essentially instantaneous process. The derivatives have acceptable shelf life and are very stable to conventional DNA synthesis conditions. Particularly preferred are those compounds wherein Ar is mono- and dihalo-substituted phenyl.

摘要:The present invention provides unified synthesis of the C1-C19 building blocks of halichondrins and analogs thereof using selective coupling of poly-halogenated nucleophiles in chromium-mediated coupling reactions. The present invention also provides a practical and efficient synthesis of C20-C38 building blocks of halichondrins and analogs thereof. Also provided herein are general methods of selective activation and coupling of poly-halogenated analogs with an aldehyde. The provided coupling reactions are selective for halo-enone and halo-acetylenic ketal over vinyl halide and halide attached to a sp hybridized carbon. The provided efficient selective coupling reactions can allow easy access to the C1-C19 building blocks and C20-C38 building blocks of halichondrins and analogs thereof with limited or no purification or separation of the intermediates.

摘要:Processes and systems for producing N-vinyl carboxylic acid amides are provided herein. According to some aspects of the present invention, a process for producing an N-vinyl carboxylic acid amide is described that eliminates interim solids handling steps during formation of the intermediate compounds, thereby increasing efficiency and reducing cost. The processes and system described herein may be used for the synthesis of N-vinylformamide and its intermediates, including 1-hydroxyethylformamide and 1-alkoxyethylformamide, or for the synthesis of N-methyl,N-vinylformamide and its intermediates, including N-methyl,1-hydroxyethylformamide and N-methyl,1alkoxyethylformamide.

摘要:A first polynucleotide is formed with a first particular sequence of nucleotides such as by providing a solid-phase support and adding nucleotides to the support. A second polynucleotide is formed in a similar manner with a second particular sequence of nucleotides which are complementary to the nucleotides in the first polynucleotide at first particular ends of the polynucleotides. The first particular ends may be the 3'-ends of the polynucleotides. The polynucleotides are hybridized or annealed at their 3'-ends to form a base-pair complementary stretch between the first and second polynucleotides. A repair synthesis is then provided in the first and second polynucleotides at second ends (such as the 5'-ends) opposite the first particular ends to provide a double-stranded polynucleotide. The repair synthesis may be monitored by labelling the second end (or 5'-end) of one or both of the nucleotides with radioactivity and then subjecting the nucleotides to an enzymatic reaction.
