Abstract

This paper describes the development of a highly convenient solution-phase methodology using volatile amines for the synthesis of β-, α,β- and α-tetrapeptoids, as an alternative to solid-phase technologies. Column chromatographic purifications are reduced to a minimum and the majority of the intermediates are purified by filtration and/or evaporation. The method is amenable to gram-scale synthesis of peptoids, and post-modification of a model peptoid by successive and selective ligations, using click thiol-ene coupling, and copper-catalysed azide-alkyne cycloaddition is demonstrated.
