Fast synthesis of benzofluorenes by selenium-mediated carbocyclizations.

Sohail A Shahzad1, Thomas Wirth.   

Abstract

When one ring is not enough: A new double cyclization of stilbene derivatives results in benzo[b]fluorenes via dihydronaphthalenes. The presence of a selenium electrophile and a Lewis acid are crucial for the formation of the C-C bonds.
