A new approach to construct 2,3-disubstituted quinolines is described via Pd-catalyzed oxidative cyclization of o-vinylanilines and alkynes with molecular oxygen. This transformation is supposed to undergo intermolecular amination of alkyne, insertion of the olefin, and oxidative cleavage of C–C bond sequence.
通过Pd催化邻乙烯基苯胺和炔烃与分子氧的氧化环化,描述了一种构建2,3-二取代喹啉的新方法。据认为,这种转变经历了炔烃的分子间胺化,烯烃的插入以及C–C键序列的氧化裂解。
