Facile assembly of 1,5-diazocan-2-ones via cyclization of tethered sulfonamides to cyclopropenes†
Abstract
The sulfonamide moiety was evaluated as an activating and stabilizing functional group in the metal-templated strain release-driven intramolecular nucleophilic addition of amines to cyclopropenes to generate 1,5-diazocan-2-ones.
