beta-(2-Aminophenyl)-alpha,beta -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.

Abstract
beta-(2-Aminophenyl)-alpha,beta -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.File in questo prodotto:
