The present invention provides lyophilized and stable lyophilized anthracycline glycoside salts, in particular, the hydrochloride salt. Also, the present invention provides methods of stabilizing these anthracycline glycoside salts, and methods for producing stable lyophilized anthracycline glycoside salts, such as for example the antineoplastic compound idarubicin hydrochloride, or the compounds doxorubicin hydrochloride, and epirubicin hydrochloride.

Starting from commercially available dyestuff intermediate, quinizarin (6) as BCD-ring synthon for anthracycline, a key intermediate 5b has been prepared by a simple reaction sequence. (+/-)-4-Demethoxydaunomycinone (4b) has been synthesized from 5b.Further 4b was coupled with L-daunosamine derivative (24) to give the requisite α-glycoside 4a.
