Two series of novel ether phospholipids (EPs) have been synthesized. The first includes cyclodecylidene-or cyclopentadecylidene-substituted EPs carrying N, N, N- trimethylammonium or N-methylpiperidino or N-methylmorpholino head groups. The second series encompasses more rigid head groups in combination with cycloalkylidene moieties in the lipid portion. In addition, hydrogenated derivatives were obtained. All the new ...
