Synthesis of a Laterally Branched Polyamine from α-Methylene-γ-butyrolactone
摘要:
A polyamine derivative was prepared from alpha-methylene-gamma-butyrolactone. This method used Michael addition and lactone aminolysis followed by the nucleophilic substitution of the hydroxyl group by an azido group. The coupling of a lipophilic alkyne led to a polyamine that will be probed as a gene transfer agent.

Herein, we report the synthesis, characterization and evaluation of the transfection efficiencies of a series of dicationic amphiphiles designed to construct quaternary ammonium ion-based cationic lipids varying in chain length of the hydrophobic back bone connected individually through head group to a 1,2,3-triazolium cation consisting of 2-hydroxy ethyl chain as substitution. Accordingly, three dicationic
