Novel Fmoc-Polyamino Acids for Solid-Phase Synthesis of Defined Polyamidoamines [PDF]
, 2011 A versatile solid-phase approach to sequence-defined polyamidoamines was developed. Four different Fmoc-polyamino acid building blocks were synthesized by selective protection of symmetrical oligoethylenimine precursors followed by introduction of a ...
