Abstract

A novel method for the preparation of aminoalkylaminomethyl products was developed utilising novel Mannich-type salts featuring a R 2NCH 2NR 3 + moiety. This methodology showed good nucleophile scope and was successfully employed in reactions under basic, acidic, and neutral conditions. A wide range of diamine products was successfully synthesised, including a neuropeptide Y antagonist.
