systems are commonly undertaken through cyclization and cycloaddition reactions, but the formation of seven- and eight-membered-ring systems are not as abundant. An efficient and high-yielding method for the synthesis of seven- and eight-membered-ring nitrogen-containing heterocycles by ring-closing metathesis is reported. uracil - azepine - azocine - ring-closing metathesis
通常通过环化和环加成反应对五元和六元环系统进行合成,但是七元和八元环系统的形成并不那么丰富。报道了一种通过闭环易位合成七元和八元环含氮杂环的高效高产方法。 尿嘧啶-氮杂-偶氮辛-闭环复分解
