Neoglycolipids bearing a paramagnetic probe in their lipophilic aglycon have been prepared. All belong to the Image -glucose series, both anomers for the glucoside representatives, respectively β and α anomers in the S- and C-glucosyl series. Two different types of radical sites have been used, a relatively short-lived imino N-oxyl group for glucosides and a more stable N-acylamino N-oxyl moiety in the other cases. EPR spectra of these radical species afforded information on the conformation of the lipophilic chain in the vicinity of the paramagnetic probe.
