The efficient synthesis of a range of heterocycle-fused benzylic azepine and azocine derivatives is reported, employing a directed metallation/ruthenium-catalysed ring-closing metathesis approach. A base-mediated tautomerisation approach can be used to access both the azepine and azocine derivatives from the same starting material.
据报道,采用定向金属化/钌催化的闭环复分解方法可有效合成一系列杂环稠合的苄基a庚因和偶氮辛衍生物。可以使用碱介导的互变异构方法来从相同的起始原料获得氮杂ze和and嗪衍生物。
