Solid-Phase Synthesis of (ω-Aminoalkyl)peptoidsUsing Azide Chemistry

Functionalized (ω-aminoalkyl)peptoids - useful molecular transporters for drugs and probes into cells - have been synthesized by a combined microwave-assisted sub-monomer peptoid synthesis with 1-amino-ω-azidoalkanes and a subsequent reduction of the azide moiety on solid supports. This method enables the preparation of unprecedented chiral amino-functionalized and PEG-type peptoids. Both the scope and limitations of this process are presented herein.
