标 题 :Method for the synthesis of pyrrole and imidazole carboxamides on a solid support
发明人:DERVAN PETER B; BAIRD ELDON
权利人:CALIFORNIA INST OF TECHN
摘要:The present invention describes a novel method for the solid phase synthesis of polyamides containing imidazole and pyrrole carboxamides. The polyamides are prepared on a solid support from aromatic carboxylic acids and aromatic amines with high stepwise coupling yields (>99%), providing milligram quantities of highly pure polyamides. The present invention also describes the synthesis of analogs of the natural products Netropsin and Distamycin A, two antiviral antibiotics. The present invention also describes a novel method for the solid phase synthesis of imidazole and pyrrole carboxamide polyamide-oligonucleotide conjugates. This methodology will greatly increase both the complexity and quantity of minor-groove binding polyamides and minor-groove binding polyamide-oligonucleotide conjugates which can be synthesized and tested.

权利人:THE TRUSTEES OF BOSTON COLLEGE
摘要:Radical cascade reactions enabling sequence-controlled ring-closing polymerization and ring-opening polymerization for the controlled synthesis of polymers with complex main-chain structures are provided. Facile syntheses leading to low-strain macrocyclic monomers consisting of the ring-opening triggers and extended main-chain structures are also provided. The present disclosure further provides methods for excellent control over polymer molecular weights and molecular weight distributions and high chain-end fidelity allows for the preparation of polymeric systems with well-defined architectures. Further provided are the general nature of the radical cascade-triggered transformations in polymer chemistry, and its application to the synthesis of polymers with diverse main-chain structural motifs with tailored functions. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

权利人:CALIFORNIA INST OF TECHN
摘要:The invention is directed to the cross-metathesis and ring-closing metathesis reactions between geminal disubstituted olefins and terminal olefins, wherein the reaction employs a Ruthenium or Osmium metal carbene complex. Specifically, the invention relates to the synthesis of α-functionalized or unfunctionalized olefins via intermolecular cross-metathesis and intramolecular ring-closing metathesis using a ruthenium alkylidene complex. The catalysts preferably used in the invention are of the general formula n wherein: n M is ruthenium or osmium; n X and X 1 are each independently an anionic ligand; n L is a neutral electron donor ligand; and, n R, R 1 R 6 , R 7 , R 8 , and R 9 are each independently hydrogen or a substituent selected from the group consisting of C 1 -C 20 alkyl, C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, aryl, C 1 -C 20 carboxylate, C 1 -C 20 alkoxy, C 2 -C 20 alkenyloxy, C 2 -C 20 alkynyloxy, aryloxy, C 2 -C 20 alkoxycarbonyl, C 1 -C 20 alkylthio, C 1 -C 20 alkylsulfonyl and C 1 -C 20 alkylsulfinyl.

标题:An apparatus and a method for the synthesis of peptides

摘要:An apparatus for use in chemical synthesis, especially peptide synthesis, comprises a synthesis chamber unit having a multiplicity of synthesis chambers, each of which has a liquid inlet and a liquid outlet, means for introducing liquid into the individual synthesis chambers and means for simultaneous removal of liquid via the liquid outlets of the synthesis chambers by regulation of the fluid pressure difference between the liquid inlets and the liquid outlets. A method for peptide synthesis using such an apparatus comprises the provision in each of the synthesis chambers of a solid-phase support material having a first, at least N-protected amino acid coupled thereto, after which a liquid deprotection reagent is introduced into the synthesis chambers. Following deprotection, the deprotection reagent is removed, after which a second, at least N-protected amino acid is introduced into each synthesis chamber in order to couple the first and second amino acids. Third, fourth, etc. amino acids may be coupled analogously. Complete removal of the deprotection reagent from the synthesis chambers and the support material can be ensured by incorporating a stable, intensely coloured dye, e.g., azorubin, in the deprotection reagent. The apparatus and the method make possible the parallel synthesis of a large number of peptides, e.g. peptides having overlapping amino acid sequences and constituting part of a longer peptide chain. The apparatus can be adapted to manual, semi-automatic or fully automatic performance of the various steps in the synthesis procedure.
