Sumamed other facts


The invention was due to the scientists from the Research Institute of the pharmaceutical company PLIVA. Azithromycin became the first representative of the new class of 15-membered macrolides known as azalides after the introduction of nitrogen in the macrocycle of erythromycin A. Its synthesis involved several steps: oximation of erithromycin A, Beckmann rearrangement of erythromycin A oxime with aromatic sulphochlorides, reduction of the produced erithromycin A iminoether, and final methylation of the nitrogen introduced in the macrocycle of erythromycin A. Because of inadequate analytical support in the late 1970s and early 1980s, the precise structure of the LD product in the Beckmann rearrangement step of azithromycin synthesis was confirmed only later as 7 and not 6 as assumed.
