Magnesium ethoxide has been shown to be a mild, safe, and scalable alternative to trimethylaluminum for the direct addition of amines to aryl nitriles to access cyclic amidines. A variety of electronically diverse oxa-, thia-, and diazepine products were successfully synthesized in moderate to high yields. Further elaboration of these compounds to 5,6-dihydroimidazobenzoxazepines, a privileged class of pharmacologically active heterocycles, highlights the utility of this method.
