Abstract

A precatalyst of FeCl2 and iminopyridine was activated in situ by a combination of diethylzinc and magnesium bromide etherate; it catalyzed the reductive cyclization of 1, 6- enynes to give pyrrolidine and tetrahydrofuran derivatives from N-and O-tethered 1, 6- enynes. The scope of the transformation was explored.
