The present invention provides a doripenem intermediate compound shown by formula (XIV), wherein PNB is p-nitrobenzyl, and HX is an acid; and when HX is a monobasic acid, n=1; and when HX is a polybasic acid, n=2. The present invention also provides a process for preparing the doripenem intermediate compound (XIV). In addition, the present invention provides a process for preparing doripenem (I) from the doripenem intermediate compound (XIV) in a simple manner, with a high yield and low production costs. The new mono-protected doripenem intermediate compound provided in the present invention contains only one protecting group, reducing the difficulty and complexity in the subsequent de-protection step by catalytic hydrogenation, increasing the yield of the catalytic hydrogenation reaction, and thus reducing the production cost of the final product. The process is easy to operate and suitable for industrialized production.
本发明提供了一种多立培南中间体化合物,其由公式(XIV)表示,其中PNB是对硝基苄基,HX是酸;当HX是单碱酸时,n=1;当HX是多碱酸时,n=2。本发明还提供了制备多立培南中间体化合物(XIV)的方法。此外,本发明提供了一种从多立培南中间体化合物(XIV)以简单方式、高收率和低成本制备多立培南(I)的过程。本发明提供的新型单保护多立培南中间体化合物仅含有一个保护基团,通过催化氢化还原去保护步骤的难度和复杂性,提高了催化氢化反应的收率,从而降低了最终产品的生产成本。该工艺操作简便,适合工业化生产。
