  Synthesis and properties of new bolaform and macrocyclic galactose-based surfactants obtained by olefin metathesis

  摘要：

  A series of galactose-based surfactants with various structures likely to display new interesting properties were synthesized. Four monocatenary surfactants were elaborated by microwave-assisted galactosylation of undecanol or 10-undecenol. These compounds were slightly soluble in water. Their tensioactive properties were determined at 45 degreesC. Olefin metathesis was used to synthesize the two single-chain bolaforms from undec-10-enyl galactopyranosides; two pseudomacrocyclic bolaforms were prepared by grafting two carbamates at O-4 and O-4' sugar positions of the single-chain bolaforms. These four surfactants are insoluble in water and undergo monolayer compression. Cyclization of these bolaforms by olefin metathesis led to macrocyclic surfactant analogues of archaeobacterial membrane components. (C) 2004 Published by Elsevier Ltd.

  A new strategy for the synthesis of a well-defined glycolipid library is presented. A highly selective cross metathesis reaction is used to diversify the lipid moiety of anomerically pure alpha- or beta-glycosides, and subsequent functionalization of the double bond allows further expansion of the diversity. These glycolipids are being investigated for their effect on the immune system, especially the CD1-mediated T-cell activation.
