Abstract: A new process for the preparation of 6-deoxyanthracyclinones of general formula I: ##STR1## wherein R represents a hydrogen atom, a hydroxy group or a lower alkoxy group is described. The process provides a total synthesis of the 6-deoxyanthracyclinones of formula I using 1,2,3,6-tetrahydro-phthalate as starting material. The obtained racemic mixture of the compounds of formula I, if desired, can be submitted to optical resolution by the conventional method of conversion to diastereomeric derivatives using a chiral resolving agent.
