set of four phosphoramidite building blocks containing a strained dibenzocyclooctyne moiety is reported, including one example equipped with a cleavable disulfide linker. Application of these amidites in solid-phase oligonucleotide synthesis yields either 5′- or 3′-cyclooctyne-modified nucleic acids. The strained cyclooctyne-bearing oligonucleotides are used in rapid and clean conjugation reactions with
报道了一组四个含有应变二苯并环辛炔部分的亚磷酰胺结构单元,包括一个配有可裂解的二硫键的实例。这些亚酰胺在固相寡核苷酸合成中的应用产生5'-或3'-环辛炔修饰的核酸。带有应变的带有环辛炔的寡核苷酸可用于与含叠氮化物(生物)分子的快速清洁偶联反应。 寡核苷酸-菌株诱导的环加成-缀合物-亚磷酰胺-生物缀合物
