摘要：

A catalytic domino spirocyclization of 1,7-enynes with simple cycloalkanes and Cyclo-1,3-dicarbonyls has been established via multiple C-C bond formations from alkynyl/alkenyl functions and dual alpha,alpha-C(sp(3))-H abstractibn/insertion The reaction involves addition, 6-exo-dig cyclization and radical coupling sequences under convenient catalytic conditions and provides a concise access to spiro cyclopenta[c]quinolines in good to excellent yields.
