中文摘要：

在可回收手性配体[QN（OH）2]2PHAL的催化下，通过不对称氨羟化或双羟化反应合成紫杉醇13-C侧链，两种方法的产率分别为39％，97％ee和52％，99％ee，其结构经1HNMR，IR和元素分析确证。

英文摘要：

The taxol 13-C side chain was synthesized by asymmetric aminohydroxylation or dihydroxy- lation of trans-cinnamate using recoverable and resued chiral ligand [ QN （OH）2 ] 2PHAL as the catalyst. The structures were confirmed by 1H NMR, IR and elemental analysis. The yields were 39% with 97%ee and 52% with 99%ee, respectively by two methods.
