An efficient, catalyst free, 1,3-dipolar cycloaddition strategy to conjugate nucleosides and nucleotides with isoxazoles under atmospheric conditions and in an aqueous environment is reported. The protocol involves chloramine-T as a practical reagent to induce in situ nitrile oxide formation and the alkyne partner is attached to the sugar residue or the nucleobase. The reactions are regiospecific,
报道了一种有效的,无催化剂的1,3-偶极环加成策略,用于在大气条件下和水性环境中将核苷和核苷酸与异恶唑偶联。该协议涉及氯胺作为诱导原位一氧化氮形成的实用试剂,炔烃配偶体附着在糖残基或核碱基上。该反应是区域特异性的,快速且高产率的。
