Abstract
Procedure for the preparation of alpha-6-dioxy-5-oxytetracycline, by means of the hydrogenation of a tetracycline derivative of the general formula (I) **(See formula)** wherein X stands for hydrogen or halogen, or for a salt thereof, characterized in that selective hydrogenation is carried out in the presence of an alloy catalyst containing at least one metal belonging to the platinum group together with at least one metal belonging to the IB group of the periodic system.
