Semisynthetic diastereomerically pure N-glycidylanthracyclines, a process for the stereoselective preparation thereof and the use thereof as cytostatics. The invention relates to anthracyclines having cytostatic activity and the formula I, which are, where appropriate, in the form of a salt with an inorganic or organic acid, ##STR1## in which R.sup.1 is hydrogen or a hydroxyl group,

The invention relates to new anthracycline derivatives having cytostatic activity and the general formula I, ##STR1## which can optionally also be in the form of an acid addition salt of physiologically acceptable inorganic or organic acids, where R.sup.1 is hydrogen or a hydroxyl group, R.sup.2 is hydrogen, a hydroxyl or a methoxy group, R.sup.3 is hydrogen or a hydroxyl group, R.sup.4 is hydrogen or a hydroxyl group, R.sup.5 hydrogen, a hydroxyl or a methoxycarbonyl group, R.sup.6 is CH.sub.2 CH.sub.3, COCH.sub.3, COCH.sub.2 OH, CHOHCH.sub.3 or CHOHCH.sub.2 OH and R.sup.7 is an organic substituent which has 2 to 6 carbon atoms and which contains at least one oxygen, nitrogen or sulfur atom or a C--C double bond or a C--C triple bond, it being possible for the double bond also to be a constituent of a heteroaromatic system and for the oxygen, nitrogen or sulfur atom to be a constituent of an open-chain or heterocyclic system, to a process for the preparation thereof and to the use thereof in a pharmaceutical.
