Abstract

The two step synthesis of a new bolaamphiphile derived from alkenyl l-rhamnosides was described. The general synthetic strategy of bolaamphiphiles derived from l-rhamnose was based on a previous work describing the synthesis of bolaamphiphiles derived from d-xylose. The conformational properties of this new compound were investigated by FTIR spectroscopy in an aqueous film in order to obtain a reference for further studies about the membrane-interacting properties. Moreover, the surface activity of this new bolaamphiphile was analyzed by Langmuir balance technology and was compared with that of the analogous bolaamphiphile derived from alkenyl D-xylosides. The findings indicate that the rhamnoside-based bolaform has an increased surface activity and a better ability to form aggregates than xyloside-based one.
