Abstract
N-Sulfonyl-2-(1-ethoxypropargyl)azetidine derivatives undergo a gold-catalyzed rearrangement in the presence of various alcohols furnishing the 2,5-disubstituted pyrroles in excellent yields (11 examples, 63–86%). Iodide or deuterium trappings of organogold intermediate as well as kinetic study confirmed the postulated cyclization/nucleophilic substitution/elimination mechanism.
