Abstract
Procédé de fabrication de 6,9-imino éther à partir de thiocyanate d'érythromycine sans isolement d'une base d'érythromycine et d'un oxime d'érythromicine, dans lequel un réagencement Beckmann d'oxime d'érythromycine a lieu avec un système de solvant biphasique comprenant du chlorure de méthylène et de l'eau en présence de triéthylamine et de bicarbonate de soude, le but étant d'obtenir un 6,9-Imino éther pur à 87-96 %. Le 6,9-imino éther est ensuite hydrogéné en 9-déoxo-9a-aza-9a-homoérythromycine, puis soumis à une méthylation réductive pour obtenir un dihydrate d'azithromicine.
