通过早期引入合成要求较高的氟甲基环氧化物官能团,实现了埃博霉素 B 衍生物 26-氟埃博霉素 B (1) 的有效合成。氟取代基的存在导致环氧化物的稳定性显着增加,从而能够耐受片段偶联步骤和最终游戏转化所需的各种反应条件。
An efficient synthesis of the epothilone B derivative 26-fluoroepothilone B (1) was realized by early introduction of the synthetically demanding fluoromethyl epoxide function. The presence of a fluoro substituent results in a remarkable increase in the stability of the epoxide, which tolerates the wide range of reaction conditions required for the fragment coupling step and end game transformations.
