A synthesis of mono- and di-vinylquinolinediones based on substitution of the halogens in 6,7-dihaloquinoline-5,8-diones by DABCO-assisted enolate ion is described. Divinylquinolines undergo 6π-electrocyclization by thermally to give the benzo[g]quinoline derivatives.
描述了基于DABCO辅助的烯醇酸根离子取代6,7-二卤代喹啉-5,8-二酮中的卤素的单乙烯基和二乙烯基喹啉二酮的合成。二乙烯基喹啉通过热作用进行6π-电环化,得到苯并[ g ]喹啉衍生物。
