Abstract

original image

Ray of light: 10a,11-Dihydro-10H-benzo[b]fluorenes were synthesized by a visible-light-catalyzed tandem cyclization of 1,6-enynes with arylsulfonyl chlorides. This method extends the scope of enyne cyclizations and represents a new synthetic application of arylsulfonyl chlorides.
