The present invention provides methods and compositions for expanding the scope of chemical reactions that can be performed during nucleic acid-templated organic syntheses. In particular, nucleic acid-templated chemistries are used to produce reaction intermediates attached to an oligonucleotide that can be used to identify the reaction intermediates and/or the resulting reaction products. The reaction intermediates then are reacted with free reactants (for example, reactants that are difficult or impractical to couple to an oligonucleotide) to produce a reaction product. This approach expands the scope of reagents useful in nucleic acid-templated syntheses to reagents that do not need to be or cannot be tethered to an oligonucleotide. The reagents, however, still permit the synthesis of reaction products attached to oligonucleotides that can be used to identify the reaction products.
本发明提供了扩大核酸引发的有机合成过程中可进行的化学反应范围的方法和组合物。特别是,核酸引发的化学反应用于产生附着在寡核苷酸上的反应中间体,而寡核苷酸可用于鉴定反应中间体和/或由此产生的反应产物。然后,反应中间体与游离反应物(例如,难以或无法与寡核苷酸结合的反应物)反应,生成反应产物。这种方法将核酸诱导合成中有用的试剂范围扩大到无需或无法与寡核苷酸连接的试剂。不过,这些试剂仍然可以合成附着在寡核苷酸上的反应产物,而寡核苷酸可用于鉴定反应产物。
