NOVEL TETRALINES, PROCESSES FOR THEIR PREPARATION, USE THEREOF FOR THE PREPARATION OF ANTHRACYCLINONES AND NEW GLYCOSIDES (ANTHRACYCLINES) OBTAINED FROM THESE ANTHRACYCLINONES

摘要

THE PRESENT INVENTION IS RELATING TO NEW TETRALINES AND THE USE THEREOF FOR THE PREPARATION OF ANTHRACYCLINONES AND ANTHRACYCLINS. These tetralines are characterized in that they contain at least one chiral carbon and conform to Formula V. FOLLOWING: BR/ (CF DRAWING IN BOPI) BR/ IN WHICH: R AND R REPRESENT A HYDROGEN ATOM, OR HALOGEN ATOM OR OCH GROUP, ON THE CONDITION THAT ONE OF THE TWO SUBSTITUENTS R OR R MUST REPRESENT OCH, ETR REPRESENT HYDROGEN ATOM OR GOLD GROUP, WHICH IS HYDROGEN OR A PROTEIN HYDROXYL GROUP. / P P APPLICATION: SYNTHESIS OF GLYCOSIDES OF GREAT VALUE THERAPEUTIC.
