The present research work focuses on two aspects. On one hand, the most successful alkaloid-derived ligands have been attached to a soluble or insoluble support covalently, but additional OsO〓 is necessary to maintain the consistent catalytic activity during the reuse of supported chiral ligand in the next AD reaction. On the other hand, immobilization of osmium tetroxide based on microencapsulation, ion-exchange techniques, and osmylation of resins has made it possible to recover and reuse of the osmium, but failed to recover the chiral ligand at the same time.
目前的研究主要集中在两个方面：一方面，将手性配体共价键合到不溶或可溶性载体上制成负载手性配体，但在重复使用负载配体时必须补充OsO〓，才能保证催化活性不降低；另一方面，将OsO〓包裹在高聚物微囊内，或运用离子交换技术或共价键合的方法将OsO〓固载在树脂、硅胶或层状双金属氢氧化物材料上，但手性配体却不能同时回收。
