Pd(II)-catalyzed three-component reactions via trapping of ammonium ylides with N-alkylquinolinium salts are reported. These reactions provided polyfunctional polycyclic tetrahydroquinolines or 4-substituted 1,4-dihydroquinolines in excellent yields (89-99% and 89-98%, respectively) with high regioselectivities and moderate to good diastereoselectivities (up to 95:5 dr) under mild reaction conditions.
Pd(II)催化的三组分反应通过捕获铵叶立德与 N-烷基喹啉鎓盐,提供了多官能团多环四氢喹啉或 4-取代的 1,4-二氢喹啉,产率优异(分别为 89-99%和 89-98%),区域选择性高,非对映选择性适中至良好(最高可达 95:5 dr),反应条件温和。
