We report a new and efficient synthetic strategy that allows access to flexible and functionalized benzocyclotrimers under mild conditions and in few steps. The Negishi cross-coupling reaction was used for the C–C bond formation, whereas intramolecular O-alkylations provided the oxepane rings.

Provided herein are analogs of unnatural nucleotides bearing predominantly hydrophobic nucleobase analogs that form unnatural base pairs during DNA polymerase-mediated replication of DNA or RNA polymerase-mediated transcription of RNA. In this manner, the unnatural nucleobases can be introduced in a site-specific way into oligonucleotides (single or double stranded DNA or RNA), where they can provide for site-specific cleavage, or can provide a reactive linker than can undergo functionalization with a cargo-bearing reagent by means of reaction with a primary amino group or by means of click chemistry with an alkyne group of the unnatural nucleobase linker.
本文提供的是非天然核苷酸类似物,它们主要带有疏水性核碱基,在 DNA 聚合酶介导的 DNA 复制或 RNA 聚合酶介导的 RNA 转录过程中形成非天然碱基对。通过这种方式,非天然核碱基可以以特定位点的方式引入寡核苷酸(单链或双链 DNA 或 RNA)中,从而实现特定位点的裂解,或者提供一种活性连接体,这种连接体可以通过与伯氨基反应或通过与非天然核碱基连接体的炔基发生点击化学反应,与载货试剂发生官能化反应。
