  To produce doxorubicin and its analogues, methyl 3alpha, 5alpha-dihydroxy-5beta-(trimethylsilylethynyl)-2alpha-nitromethylcyclohexane-1beta-carboxylate acetonide is condensed with 1,4-dihydro-4,4,5-trimethoxy-1-oxonaphthalene in the presence of 1,8-diazabicyclo-[5.4.0]undec-7-ene in an aprotic solvent to produce 3-[(2beta-carbomethoxy-4beta-ethynyl-4alpha, 6alpha-(di-0-isopropylidenyl)cyclohexanyl-1-yl]-nitromethyl-4,4,5-trimethoxy-1-oxo-1,2,3,4-tetrahydronaphthalene, which is cyclized to produce 9beta-ethynyl-12-hydroxy-7alpha,9alpha-(di-0-isopropylidenyl)-6-nitro-4,5,5-trimethoxy-5,5a,6,6a,7,8,9,10,10a,11-decahydro-11-naphthacenone. The decahydro-11-naphthacenone is converted to 7alpha-9alpha,(di-0-isopropylidenyl)-4,5-dimethoxy-9beta-ethynyl-12-hydroxy-6-nitro-6,6a,7,8,9,10,10a,11-octahydro-11,-naphthacenone. The octahydro-11-naphthacenone is oxidized to 7alpha-9alpha, (di-0-isopropylidenyl)-9beta-ethynyl-11-hydroxy-4-methoxy-6-nitro-7,8,9,10,-tetrahydro-5,12-naphthacenedione which is converted to 6-desoxy-6-nitrodaunomycinone, daunomycinone and related 6-substituted analogues of daunomycinone.

  为了生产阿霉素及其类似物，需要将甲基3α，5α-二羟基-5β-(三甲基硅乙炔基)-2α-硝基甲基环己烷-1β-羧酸乙酸酯与1,4-二氢-4,4,5-三甲氧基-1-氧代萘醌在无极性溶剂中，在1,8-二氮杂双环[5.4.0]十一烷-7-烯的存在下进行缩合反应，产生3-[(2β-羧甲氧基-4β-乙炔基-4α，6α-(二异丙亚基)环己基-1-基]-硝基甲基-4,4,5-三甲氧基-1-氧代-1,2,3,4-四氢萘烯，然后将其环化产生9β-乙炔基-12-羟基-7α，9α-(二异丙亚基)-6-硝基-4,5,5-三甲氧基-5,5a,6,6a,7,8,9,10,10a,11-十氢-11-萘酮。 十氢-11-萘酮转化为7α-9α，(二异丙亚基)-4,5-二甲氧基-9β-乙炔基-12-羟基-6-硝基-6,6a,7,8,9,10,10a,11-八氢-11-萘酮。 八氢-11-萘酮氧化为7α-9α，(二异丙亚基)-9β-乙炔基-11-羟基-4-甲氧基-6-硝基-7,8,9,10,-四氢-5,12-萘醌，然后转化为6-去氧-6-硝基多柔霉素酮，多柔霉素酮及相关的多柔霉素酮6-取代物。
