ADENNE DERIVATIVES HAVING A SUBSTITUTED 6-AMINO GROUP AND PROCESS FOR THEIR PREPARATION

摘要

Nicotinamide 6-(2-hydroxy-3-carboxy-propylamino) purine dinucleotide is prepared by reacting nicotinamide-adenine-dinucleotide with 3,4 epoxybutanoic acid in the presence of perchloric acid to prepare an intermediate wherein the adenine nucleus is alkylated in the N1 position. That intermediate is subjected to chemical reduction of the nicotinamide ring, followed by rearrangement to yield the end product wherein the amino group in position 6 of the adenine ring is alkylated.
