Synthesis and cytotoxicity properties of novel C-2′ analogues of paclitaxel are described. The analogues were synthesized using Holton's β-lactam approach to append the side chain on baccatin III. The key intermediate to the synthesis of novel analogues was prepared employing an unprecedented stereocontrolled addition of Grignard reagent to a chiral azetidine-2,3-dione.
描述了紫杉醇的新型C-2'类似物的合成和细胞毒性。使用Holton的β-内酰胺方法合成类似物,以将侧链附加在浆果赤霉素III上。合成新型类似物的关键中间体是通过将格氏试剂空前地立体控制地添加到手性氮杂环丁烷2,3-二酮中来制备的。
