DNA-compatible chemistry restricts the types of chemical features that can be incorporated into DNA-encoded libraries (DELs). Here, a method to synthesize DNA-conjugated polycyclic isoxazolidines via a [3 + 2] nitrone-olefin cycloaddition is described. The reaction is compatible with many olefin-containing substrates and diverse N-alkylhydroxylamines. The ability to perform subsequent DNA ligation and

化学的有限范围限制了可纳入DNA编码文库(DEL)的
化学特征的类型。在此,描述了通过[3 + 2]硝酮-烯烃环加成合成DNA缀合的多环
异恶唑烷的方法。该反应与许多含烯烃的底物和各种N-烷基
羟胺相容。还证实了进行后续DNA连接和PCR扩增的能力。这种方法有助于合成包含具有未开发
化学特征的地形复杂化合物的DEL。
