Synthesis of anthracyclinone precursor: 5,12-dihydroxy-1,3,4- trihydronaphthacene-2,6,11-quinone
Tririya, Gasirat,Zanger, Murray

Two practical and efficient approaches for preparing large quantities of 5,12-dihydroxy-1,3,4-trihydronaphthacene-2,6,11-quinone 9 are described. Both synthetic approaches involve a simple route with a fewer number of steps and utilize readily available and inexpensive starting materials. Large-scale production of this precursor may prove to be useful for further research involving the synthesis of antineoplastic anthracyclines and development of their analogs with increased activity and decreased toxicity.

p-Aminophenols are provided having the structure STR1 wherein m is 0, 1 or 2; n is 0, 1, 2 or 3; R1 and R2 may be the same or different and are H, hydroxy or alkoxy; R3 is H, lower alkyl, alkanoyl or aroyl and R4 is H, lower alkyl or alkanoyl, and including acid-addition salts thereof. These compounds are useful as inhibitors of leukotriene production and as such are useful as antiallergy, anti-inflammatory and anti-psoriatic agents.
A novel racemization mechanism for the α-hydroxy ketone moiety(C9-position) of optically active anthracyclinone derivatives
Terashima,Tamoto
, p. 2589 - 2592 (2007/10/02)
The facile acid-catalyzed racemization of optically active anthracyclinone derivatives((S)(+)-1a,b) was found to proceed through the ring-expanded seven-membered α-hydroxyketones(2 and/or 3 for (S)(+)-1a) by subjecting various plausible intermediates to t
