Mono-, bis-, and tris-O-(substituted phenoxyacetyl) inosines were prepared and assayed for hypolipidemic activities in rats. Analyses of their proton magnetic resonance spectra led to the assignment of C-proton on the ribose ring. In particular, the structure of 3', 5'-O-bis [α-(p-chlorophenoxy) isobutyryl] inosine was confirmed by the shift of C3'-and C5'-proton to a lower magnetic field.
