β-(2-Aminophenyl)-α,β-ynones react with enamines of cyclic ketones by domino [2+2]cycloaddition/annelation reaction giving rise to bicyclo[4.2.0]-octane[7,8-c]-2-aryl quinolines or to c-fused quinolines. The reactivity of ynones towards acyclic enamines and thermal rearrangement of tetracyclic to the corresponding tricyclic derivatives are also described.
β-(2-氨基苯基)-α,β-炔酮通过多米诺[2 + 2]环加成/退火反应与环酮的烯胺反应,生成双环[4.2.0]-辛烷[7,8- c ] -2 -芳基喹啉或c-稠合喹啉。还描述了炔酮对无环烯胺的反应性和四环到相应的三环衍生物的热重排。
