标题 :Long-chain dna synthesis using non-natural base
发明人：MASAKI YOSHIAKI
权利人:TOKYO INST TECH
摘要:The purpose of the present invention is to provide a method for synthesizing a long-chain nucleic acid (particularly DNA) with high accuracy. The present invention provides a method for synthesizing a long-chain nucleic acid, the method comprising using: (i) a nucleoside-3'-O-phosphoramidite derivative having a non-natural nucleic acid base; or (ii) a nucleoside-3'-O-phosphoramidite derivative having a non-natural nucleic acid base and a nucleoside-3'-O-phosphoramidite derivative having a natural nucleic acid base in the chemical synthesis of a nucleic acid based on the phosphoramidite method.

摘要:Photon generating substrates for light-directed oligonucleotide synthesis are disclosed. Light is generated within a solid-state stack that supports growing oligonucleotides. The light may be generated by microLEDs, a pass-through liquid crystal panel, or an LCoS system. Light passes through a transmissive layer on which growing oligonucleotides are attached. Patterning of the light is controlled by selective activation of the microLEDs or by selective control of the transparency of a liquid crystal layer. Photolabile blocking groups are selectively removed by exposure to patterned light emitted from the photon generating substrate.

标 题 :Process for adding on compounds containing carbon anions
发明人：SCHAEFER HANS
权利人:BASF AG
摘要:A process for adding on compounds containing carbon anions to olefinic compounds in which the double bond is not activated, which comprises the anodic oxidation of compounds containing carbon anions in the presence of both an olefinic compound in which the double bond is not activated and a polar solvent. The products are suitable for further synthesis and for the production of biologically active substances.
