The purpose of this thesis is just to search a novel synthesis of thiourea, and to use thiourea in dealing with the waste water from the production of phthalic anhydride, and the application of thiourea in solid-state reactions at low heating temperature was also studied.

本论文研究的目的就是寻找一种合成硫脲新的工艺过程，且尝试以合成得到的产物硫脲应用于工业苯酐废水的处理，同时对硫脲在低热固相化学中的应用进行了初步的探索。

The present dissertation reviews the total synthesis of biotin, particularly on Hoffmann-La Roche\'s Lactone-Thiolactone approach. The Lactone-Thiolactone approach is presently the most competitive commercial route, which gives an excellent illustration of the gradual construction of the functionalized skeleton with the simultaneous solution of the stereochemical issues in a minimal number of steps.In 1970, Gerecke etc. of Roche Corp.

论文对生物素全合成的文献进行了综述，重点讨论了目前工业上最有竞争力的内酯—硫代内酯路线，展示了生物素是如何以最少的步骤去逐步构建目标产物的官能团骨架并同时解决立体化学问题的。1970年，Roche公司的Gerecke等报道了一条通过手性内酯，以较高收率并保持构型得到手性硫代内酯，从而直接合成d-生物素的方法后，该中间体内酯(3aS，6aR)-1，3-二苄基。
