A palladium-catalyzed annulation of ortho-vinylanilines with dimethyl sulfoxide was developed to access 4-aryl quinolines in moderate to good yields. Activated by 1,4-diazabicyclo[2.2.2]octane bis(sulfur dioxide) adduct (DABSO), DMSO served as a "[double bond, length as m-dash]CH-" fragment in this transformation. It represents a facile pathway leading to 4-aryl quinolines.
开发了一种钯催化的邻乙烯基苯胺与二甲基亚砜的环化反应，以中等至良好的产率获得4-芳基喹啉。在1,4-二氮杂双环[2.2.2]辛烷双（二氧化硫）加合物（DABSO）的活化下，二甲基亚砜在该转化中充当“[双键，长度如m破折号]CH-”片段。它代表了一条通往4-芳基喹啉的简便途径。
