A series of highly functionalized 2-pyrrolines have been constructed by using a novel FeCl(3)-catalyzed reaction of aziridines with arylalkynes, in which an aryl-substituted alkenyl cation is involved.

Silver forges the ring: A new and practical silver‐catalyzed [5+2] cycloaddition method has been developed for the synthesis of azepines through the formation of four new chemical bonds between a γ‐amino ketone and an alkyne in one step. This method provides a new hetero‐[5+2] cycloaddition strategy for the construction of seven‐membered ring systems.
