制备

以7-ACA为原料，对7位氨基和2位羧基保护后，再与三苯基磷反应得磷化物，它在碱性条件下与甲醛进行Wittig反应得3位的乙烯基衍生物(I)。用盐酸处理使7位的氨基游离而得化合物(Ⅱ)。在N-三甲基硅基乙酰胺存在下，化合物(Ⅱ)和4-溴乙酰乙酰溴在乙酸乙酯中，于-10℃下反应1h，得酰化产物(Ⅲ)，收率88％。化合物(Ⅲ)在二氯甲烷和乙酸中，用亚硝酸钠水溶液在-5℃亚硝化30min，再加入尿素破坏过量的亚硝酸钠，得到定量收率的羟胺化合物(Ⅳ)。化合物(Ⅳ)在N，N-二甲基乙酰胺中，和硫脲于5℃反应1h，环合得到化合物(V)。粗品化合物(V)在苯甲醚中，和三氟乙酸在5℃下反应1h，然后用水重结晶，即得头孢地尼.
