A useful extension of the Marschalk reaction directed toward synthesis of 11-deoxydoxorubicin antitumor antibiotics.. Tetrahedron Letters 1983 , 24 (44) , 4809-4812. DOI: 10.1016/S0040-4039(00)94013-9.

The enantiomer -18 was obtained by Marschalk reaction of 7 with the chiral building block 20 derived from (S)-lactic acid. A similar reaction sequence converted -18 to -1 thus proving natural We describe herein a simple method for the derivatization of 1,4‐dihydroxyanthraquinone through a modified Marschalk reaction.
