When nitric oxide was bubbled into acetonitrile under aerobic conditions, the solution showed a cobalt-blue color. Addition of guanosine into the solution generated N2-acetylguanosine as a major product. The result of the reaction using 15N labeled acetonitrile indicated that the nitrogen atom of the acetylated exocyclic amino group on N2-acetylguanosine originated from acetonitrile. We discuss the reaction mechanism for the acylation.
当一氧化氮在有氧条件下通入乙腈时,溶液出现钴蓝色。向溶液中加入鸟苷后,生成以N2-乙酰鸟苷为主要产物。使用15N标记的乙腈进行反应的结果表明,N2-乙酰鸟苷上的乙酰化出环氨基团的氮原子来自乙腈。我们讨论了酰化的反应机制。
