A Divergent Synthesis of Polyurethane Dendrimers
Published: 31 October 2013 by MDPI in The 17th International Electronic Conference on Synthetic Organic Chemistry session Polymer and Supramolecular Chemistry
Abstract: Utilizing diphenylphosporyl azide (DPPA) to promote the Curtius reaction, we report a divergent synthesis of several dendrimers. The synthetic scheme involves several diol and triol core molecules. Each generation is propagated through reaction with 3,5-bis(3-acetoxypropyloxy)benzoic acid and DPPA. The generations for each core are characterized by HNMR, CNMR and MALDI-TOF MS.We had previously reported a convergent synthesis of structurally different polyurethane dendrimers and discuss the modification made to facilitate the preparation of these dendrimers.We had previously reported a convergent synthesis of structurally different polyurethane dendrimers.
