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

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.
