Continuousflow technology has been applied to C−H activation to improve reaction efficiency. Various imines and alkynes have been smoothly applied to continuousflow system, and the spirocyclic sultams and isoquinolines can be obtained in excellent yields in a relatively short time via [3+2] or [4+2] annulation reactions.

Cp*Co-III-catalyzed tandem inert C-H alkenylation/annulation of N-sulfonyl ketimines with alkynes is revealed. A series of spiro indenyl benzosultams were facilely prepared in good yields under mild reaction conditions.
