摘要: 对2-碘-9-苄基嘌呤与有机锡试剂RSnBu3之间的Stille偶合反应以及2-乙烯基-9-苄基嘌呤中的乙烯基的亲核加成和环加成反应进行了研究,合成出了一系列新的2位取代的嘌呤衍生物.化合物的结构均经元素分析、1HNMR、13CNMR和MS确证.提出2-乙烯基-9-苄基嘌呤与苯硫酚的反应机理为氧化加成而非亲核加成,采用单晶X射线衍射法对主要产物的结构进行了确认.

Abstract: The Stille coupling reaction between 2-iodo-9-benzylpurine and RSnBu3and the nucleophilic addition and cycloaddition of 2-vinyl-9-benzylpurine were studied. Aseries of new 2-substituted purined-erivatives were synthesized and characterized by elemental analysis, 1HNMR, 13CNMR and MS. It was demonstrated that the reaction mechanism between 2-vinyl-9-benzylpurine and benzenethiol was oxidative addition rather than nucleophilic addition. The structure of the main product was determined by single-crystal X-ray method.

Key words: 2-Iodo-purine, 2-Vinyl-purine, Stille coupling, Nucleophilic addition, Cycloaddition
