Abstract

A practical synthetic route to a terminally trifluoromethylated analogue of the ganglioside GM1 is described. It is based on regioselective chemical manipulation of naturally occurring GM1 isolated from bovine brain. Lyso-GM1 obtained by simple chemical transformation was then simply acylated with the NHS ester of trifluorostearic acid. The ability to attach fluorinated acyl chains of different lengths to glycosphingolipids is expected to have broad applicability in chemical biology and mass spectral imaging of soft tissue.
