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。

The simultaneous determination of sulfamic acid and DL-malic acid in environmental friendly electropolishing solution by ion chromatography was described. Sulfamic acid and DL-malic acid were well separated by using Metrosep A Supp 5 150 anion exchange column for separation and 3.2 mmol/L Na2CO3-1.0 mmol/L NaHCO3 as eluent.

采用Metrosep A Supp5150阴离子分离柱，以3.2mmol/L Na2CO3-1.0mmol/L NaHCO3为淋洗液，氨基磺酸和DL-苹果酸可得到很好的分离，使用离子色谱为检测手段可实现环保型电镀抛光液中氨基磺酸和DL-苹果酸的同时测定。
