A modified synthetic route to combretastatin D-2 (5) was devised in order to further evaluate its biological activity, for its conversion to phosphate prodrugs (25−28), and as a route to obtaining dihydro-combretastatin D-2 (42). A parallel first total synthesis of dihydro-combretastatin D-2 was completed, proceeding from a saturated 3-phenylpropionic ester intermediate via the Ullmann biaryl ether
设计了一种改良的考布他汀 D-2 ( 5 )合成路线,以进一步评估其生物活性,将其转化为磷酸盐前药 ( 25 - 28 ),并作为获得二氢考布他汀 D-2 ( 42 )的途径. 从饱和的 3-苯基丙酸酯中间体开始,通过 Ullmann 联芳醚反应 ( 39 - 41 ) ,完成了二氢考布他汀 D-2 的平行第一次全合成。与考布他汀 D-2 表现出的癌细胞生长抑制活性相反,相对较小的结构修饰 ( 41 , 42 ) 导致这些特性的消除。
