synthesize cis-fused dihydrobenzo[c]phenanthridinones. The amide group functions as a directing group as well as a leaving group and provides an easy access to the pharmaceutically useful benzo[c]phenanthridinealkaloids such as nitidine and fagaronine analogues. The present methodology is compatible with various functional groups with respect to azabicyclic alkenes and aromatic amides. The reaction mechanism
已开发出一种高效的钌 (II) 催化串联 C-C/C-N 键与芳基酰胺和 7-氮杂苯并降冰片二烯形成合成顺式稠合二氢苯并[ c ]菲啶酮。酰胺基团起导向基团和离去基团的作用,并提供了一种容易获得药学上有用的苯并[ c ]菲啶生物碱如尼替丁和法加罗宁类似物的途径。本方法与关于氮杂双环烯烃和芳族酰胺的各种官能团相容。氘标记研究提出并支持了涉及定向基团辅助 C-H 活化的反应机制。
