权利人:TRUSTEES 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.

摘要:Disclosed is a process for the synthesis of 1,3,3,3-tetrafluoropropene which comprises, in one embodiment, reacting a compound of CF 3 X 1 with a compound of CX 2 Hâ•?CHX 3 , wherein X 1 , X 2 , and X 3 are each independently selected from the group consisting of fluorine, chlorine, bromine and iodine, to produce a reaction product comprising a compound of CF 3 CHâ•?CHX 3 , wherein X 3 is as described above; and when X 3 is not fluorine, fluorinating the compound to produce 1,3,3,3-tetrafluoropropene. The process in another embodiment comprises preparing tetrafluoropropene comprising thermally cracking one or more compounds capable of producing a reaction mixture which preferably comprises diflurocarbene radicals and vinylidene fluoride, and converting said reaction mixture into—tetrafluoropropene (1,3,3,3-tetrafluoropropene).

摘要:The present invention relates to synthesis of bio-conjugates and well-defined multivalent protein dendrimer assembly by a general and straightforward chemo- enzymatic method. The method involves a simple two-step process in which proteins appended with an orthogonal label by facile sortase-mediated ligation are conjugated to a multivalent dendritic scaffold using the versatile copper-catalyzed azide-alkyne cycloaddition reaction. The 'Sortase-Click' strategy produces satisfactory yield of dendrimers under mild conditions from readily available His6 -tagged proteins and serves as a powerful general strategy for covalent assembly of bio-conjugates and protein dendrimers.

标 题:Device for the synthesis of dimeric species
发明人：MCBAY HENRY RANSOM CECIL; MCBAY LEGAL REPRESENTATIVE BY
摘要:A compact, continuous-flow synthesis device for the production of dimeric hydrocarbon species by reacting unsaturated hydrocarbons such as alkenes and alkynes with atomic hydrogen or free radicals generated by the dissociation of molecular hydrogen or organics such as alkanes. The dissociation is carried out in a module either by the electric discharge between a pair of parallel, annular, flat disc, high-voltage electrodes or by the radiation between a pair of parallel, toroidal ultraviolet lamps. The reactant to be dissociated flows radially inward from the module periphery between the pair of electrodes or the pair of ultraviolet lamps, and reaches the axis of the annulus or torus in the dissociated state. Unsaturated hydrocarbons in the dispersed phase injected vertically down this axis react with the dissociated species in a collision chamber surrounding the dissociation module to form residual free radicals. Cooling the residual free radicals then converts them to condensed dimeric products in a collection basin adjacent to the collision chamber. Many dimeric species, such as 2,2,3,3-tetramethylbutane, can be produced from different starting materials. The device also generates dimeric products from the reaction of free radicals alone in the absence of unsaturated hydrocarbons.

摘要:The present invention relates to synthesis, purification and methods to obtain high purity novel 2′-arabino-O-methyl nucleosides and the corresponding phosphoramidites of various arabinonucleoside bases and introduction of such units into defined sequence synthetic DNA and RNA. Various synthetic oligonucleotides, such as HIV integrase inhibitor 14-mer and thrombin binding oligonucleotide, thrombin-1, bearing ara-2′-omethyl modification have been synthesized. It is anticipated the oligonucleotides incorporating these monomers will exhibit biological activities related to antisense approach approach, design of better SiRNA's, diagnostic agents. Similarly, it is anticipated that oligonucleotides incorporating such novel nucleosides will be useful to develop therapeutic candidates designing stable G-quadruplexes and Aptamers for oligonucleotide structure, folding topology, evaluation of biochemical properties and design and develop as therapeutic agents. It is further anticipated that the nucleosides, phosphates and triphosphates of this invention could develop as therapeutic agents.
