Abstract

Procedure for the preparation by synthesis of N-substituted lactose of general formula: **(See formula)** where: n represents an integer equal to 3 or 4, m represents an integer with a value from 1 to 3, and R, R1 can both have the same or different meanings and can represent a hydrogen atom, an alkyl radical, preferably of 1-3 carbon atoms, an alkenyl, alkynyl or aryl radical, or they can be part of a heterocycle together with the atom nitrogen, characterized in that a cyclic anhydride is reacted with an appropriate amino acid, one of the carbonyl groups of the resulting amide is then selectively reduced and, finally, the carboxylic acid is transformed into the corresponding amide.
