quinolines from 2-alkenylanilines has been described; the reaction involves an unexpected DMAP-catalyzed cyclization of 2-alkenylanilines with di-tert-butyl dicarbonate (Boc2O, 2.0 equiv), and a series of tert-butyl quinolin-2-yl carbonate with various functional groups have been synthesized in good yields under mild conditions. Furthermore, the tert-butyl quinolin-2-yl carbonate can be easily converted into
已经描述了由2-链烯基苯胺快速合成喹啉的新方法。所述反应涉及2- alkenylanilines与二意想不到DMAP催化环化叔丁基酯(BOC 2 O,2.0当量),和一系列叔与各种官能团中,已经合成丁基喹啉-2-基碳酸酯在温和的条件下丰产。此外,碳酸叔丁基喹啉-2-基碳酸酯可以容易地转化为相应的喹啉酮和2-(假)卤代喹啉。
