Depending on their production or origin pharmaceutical agents can be split into three groups : Totally synthetic material ( synthetics ) Natural products , and Product from partial syntheses ( semi- synthetic products ) 依据其生产或来源，药物制剂可以分为三类： I. 完全的合成材料（人工合成材 料），II. 天然产物，和 III. 源自部分合成的产品（半合成产品） 。 2. The emphasis of the present book is on the most important compounds of groups I and III - thus Drug synthesis. 翻译：所以本书的重点是 I 和 III 部分的药物合成。 本书的重点是在于Ⅰ和Ⅲ类中最重要的化合物——药物合成。 3. This does not mean, however , that natural products or other agents are less important . 然而这并不意味着，天然产物和其他试剂不重要。 4. they can serve as valuable lead structures , and they are f requently needed as starting materials or as intermediates fo r important synthetic products . 它们可以作为有价值的先导结构，他们常常作为重要的合成产品的起始原料或 中间体产品。 5：Table 1 gives an overview of the different methods for obtaining pharmaceutical agents. 表 1 列出了获取药物制剂的不同方法的概述。 6.
