Abstract
AbstractA metal‐free [4+1] annulation of in‐situ generated ortho‐quinone methides (o‐QMs) and CF3−imidoyl sulfoxonium ylides (TFISYs) has been achieved under mild conditions, which provides a facile and straightforward access to a variety of trifluoromethyl‐containing 2,3‐dihydrobenzofurans in moderate to excellent yields.
