A novel method for the preparation of aminoalkylaminomethyl products was developed utilising novel Mannich-type salts featuring a R2NCH2NR3+ 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.
