标题:Synthesis of dithioester chain transfer agents and use of bis(thioacyl) disulfides or dithioesters as chain transfer agents
发明人：RIZZARDO ENZIO; THANG SAN HOA; MOAD GRAEME
权利人:E I DUPONT NEMOURS AND COMPANY; COMMW SCIENT IND RES ORG
摘要:This invention relates to the synthesis of dithiocarboxylic acid esters by reaction of bis(thioacyl) disulphides, thioacetals or vinylidane bis(thioether) with free-radicals (optionally in the presence of monomers). The invention also relates to processes for the synthesis of polymers utilising these dithioesters as polymerisation regulators (chain transfer agents) or to the use of bis(thioacyl) disulphides to generate dithioester chain transfer agents in situ.

标 题:Synthesis of oligonucleotide arrays using photocleavable protecting groups
发明人：MCGALL GLENN H; NAM NGO QUOC
权利人:AFFYMETRIX INC
摘要:Novel compounds are provided which are useful as linking groups in chemical synthesis, preferably in the solid phase synthesis of oligonucleotides and polypeptides. These compounds are generally photolabile and comprise protecting groups which can be removed by photolysis to unmask a reactive group. The protecting group has the general formula Ar-C(R1)(R2)-O-C(O)- wherein: Ar is an optionally substituted fused polycyclic aryl or heteroaromatic group or a vinylogous derivative thereof; R1 and R2 are independently H, optionally substituted alkyl, alkenyl or alkynyl, optionally substituted aryl or optionally substituted heteroaromatic, or a vinylogous derivative of the foregoing; and X is a leaving group, a chemical fragment linked to Ar-C(R1)(R2)-O-C(O)- via a heteroatom, or a solid support; provided that when Ar is 1-pyrenyl and R1=R2=H, X is not linked to Ar-C(R1)(R2)-O-C(O)- via a nitrogen atom. Preferred embodiments are those in which Ar is a fused polycyclic aromatic hydrocarbon and in which the substituents on Ar, R1 and R2 are electron donating groups. A particularly preferred protecting group is the 'PYMOC' protecting group, pyrenylmethyloxycarbonyl, where Ar=pyrenyl and R1=R2=H. Also provided is a method of forming, from component molecules, a plurality of compounds on a support, each compound occupying a separate predefined region of the support, using the protected compounds described above.

标 题:Synthesis of 2-aralkoxyadenosines and 2-alkoxyadenosines
发明人：MOORMAN ALLAN R
权利人:KING PHARMACEUTICALS RES & DEV
摘要:The invention provides new methods for synthesis of 2-aralkyloxyadenosines and 2-alkoxyadenosines. The invention is particularly useful for synthesis of 2-[2-(4-chlorophenyl)ethoxy]adenosine. Preferred methods of the invention include activating a guanosine compound followed by hydrolysis; alkylating the hydrolyzed compound with subsequent animation to provide a 2-aralkyloxyadenosine or a 2-alkoxyadenosine compound.

发明人：VON WOLFF NIKLAS; CHAR JOËLLE; CANTAT THIBAULT
权利人:COMMISSARIAT ENERGIE ATOMIQUE
摘要:A one pot single step process is described for the synthesis of a compound, including a labeled compound, containing a sulfonyl functional group comprising the step of mixing together a silane, an SO 2 source, an electrophilic compound, an activating compound and optionally a metal catalyst. A process for producing tracers from a labeled sulfonyl containing compound prepared by the described process is also included.
