Bis-MPA (or 2,2-Bis(methylol)propionic acid) is an aliphatic, pro-chiral molecule comprised of two hydroxyls and one carboxylic group that has been used in the synthesis of many different types of polymers. Dendrons synthesized from bis-MPA are biodegradable and have low cytotoxicity, making them well suited for use in biological research applications. These materials have been used in many applications such as signal amplification in bioassays and in drug delivery applications. These alkyne-functionalized dendrimers can be readily functionalized using either copper(I)-catalysed alkyne-azide cycloaddition (CuAAC), strain-promoted alkyne-azide cycloaddition (SPAAC), or thiol-yne click reactions. Additionally, the amine-functionalized core can be readily used in EDC or DCC coupling reactions (after Boc deprotection) with carbonyl-containing compounds to yield highly functionalized materials for a variety of biomedical applications.
