Cyclizations via Frustrated Lewis Pairs: Lewis Acid Induced Intramolecular Additions of Amines to Olefins and Alkynes

Abstract

Intramolecular additions of amines to olefinic and acetylenic residues in the presence of B(C6F5)3 affords a “frustrated Lewis Pair” strategy to five- and six-membered-ring heterocyclic ammonium borate derivatives (see picture).
