ring-closing metathesis (RCM) leading to the synthesis of benzo-fused heterocycles was demonstrated by using a ruthenium-mediated isomerization followed by a ruthenium-mediated RCM reaction. This resulted in the syntheses of a variety of products including two substituted benzo[1,4]dioxins, a naphtho[2,3-b][1,4]dioxin, a 2H-chromene and a benzo[b]furan.
通过使用钌介导的异构化和钌的合成,证明了将芳基烯丙基醚和芳基烯丙基用作掩蔽的乙烯基醚和1-丙烯基苯基用于闭环复分解(RCM),导致合成苯并稠合的杂环。介导的RCM反应。这导致了多种产物的合成,包括两种取代的苯并[1,4]二恶英,萘并[2,3- b ] [1,4]二恶英,2 H-色烯和苯并[ b ]呋喃。
