Abstract: Reduction of 0-lactosylnitromethane, j3-cellobiosylnitrome thane, and ß-maltosylnitromethane with ferrous hydroxide in situ afforded jS-lactosyl- methylamine, 0-cellobiosylmethylamine, and 0-maltosylmethylamine. In the prepared derivatives the primary amino group, in comparison to the primary hydroxyl group, causes a shift of the 13C NMIR signal of the a-carbon towards higher values of magnetic field. The primary nitro group in the nitro-precursors exhibits an opposite effect. The INEPT pulse technique was used to assign the signals of the nitromethyl carbon atoms.
