Radical cyclization of benzene-tethered 1,7-enynes with aryldiazonium tetrafluoroborates: a facile route to benzo[j]phenanthridines

Author affiliations

Abstract

A radical cyclization of benzene-tethered 1,7-enynes with aryldiazonium tetrafluoroborates in the presence of copper(II) acetate and DABCO˙(SO2)2 is developed. This transformation is triggered by arylsulfonyl radicals which are generated in situ from aryldiazonium tetrafluoroborates and DABCO˙(SO2)2. This procedure is compatible with a wide range of functional groups, providing a facile route for the synthesis of diverse benzo[j]phenanthridines.
