Abstract
下面式II的新蒽环酮及其制备方法,该新蒽环酮是用于制备抗肿瘤苷的有用中间体。
Description
本发明涉及新的式Ⅱ4-脱甲氧-4-氨基正定霉素酮,其是制备抗肿瘤的蒽环苷的有用中间体,本发明还涉及其制备方法:
Ⅱ
式Ⅱ的正定霉素酮衍生物可通过下面所述方法制备:
(a)通过氢解除去式(Ⅴ)洋红霉素酮(Carminomycinone)的7α-羟基;
(b)在N,N-二异丙基乙胺和催化量的4-二甲氨基吡啶存在下,使生成的4-脱甲氧基-7-脱氧正定霉素酮(式Ⅵ)与4-
氟苯磺酰氯反应;
(c)使生成的4-脱甲氧基-4-O-〔4-氟苯磺酰基〕-7-脱氧正定霉素酮(式Ⅶ)与苄胺反应;
(d)通过催化氢化,从生成的4-脱甲氧基-4-苄氨基-7-脱氧正定霉素酮(式Ⅷ)中脱去苄基;
(e)通过用三氟乙酸酐处理,将得到的4-脱甲氧基-4-氨基-7-脱氧正定霉素酮(式Ⅸ)的4-氨基加以保护,
(f)重新把7α-羟基引入到生成的式(Ⅻ)化合物中,得正定霉素酮衍生物(式Ⅱ)的受保护衍生物(式ⅩⅢ);
ⅩⅢ
(g)从受保护的衍生物(式ⅩⅢ)中脱去4-氨基保护基,得到正定霉素酮衍生物(式Ⅱ):
图示Ⅰ
上述方法用上面的图示Ⅰ详细说明。该方法的起始化合物为天然的洋红霉素酮(Carminomycinone)式(Ⅴ)。步骤(b)的磺酰化反应仅生成取代的C-4-O-磺酰基衍生物(Ⅶ),其余的C-6-OH和C-11-OH均不受影响。应该强调指出,仅在所述条件下,获得了未曾预料到的选择性。
反应(c)在蒽环化学中是新的反应,反应(c)可能是由于醌基团和C-4位置上的4-氟苯磺酰基拉电子作用的结果。该反应最好在四氢呋喃中于室温下进行。步骤(e)用三氟乙酸酐进行。步骤(f)可以按照C.M.Wong等所述方法〔Can.J.Chem.,51,446(1973)〕进行。用乙二醇处理,可以有效地保护4-脱甲氧基-4-(受保护的氨基)-7-脱氧正定霉素酮(式Ⅻ)的13-酮基;将生成的化合物7-位溴化;水解7-溴和13-缩酮基,得到4-脱甲氧基-4-N-三氟乙酰氨基正定霉素酮(式ⅩⅢ),
溴化反应一般在2,2′-偶氮双(异丁腈)存在下用溴或N-溴代琥珀酰亚胺进行。
