Neoglycolipids bearing a paramagnetic probe in their lipophilic aglyco
n have been prepared. All belong to the D-glucose series, both anomers
for the glucoside representatives, respectively beta and alpha anomer
s in the S- and C-glucosyl series. Two different types of radical site
s have been used, a relatively short-lived imino N-oxyl group for gluc
osides and a more stable N-acylamino N-oxyl moiety in the other cases.
EPR spectra of these radical species afforded information on the conf
ormation of the lipophilic chain in the vicinity of the paramagnetic p
robe.
