The totalsynthesis of a bis-cyclopropane analog of the antimitotic natural product (−)-disorazole C1 was accomplished in 23 steps and 1.1% overall yield. A vinyl cyclopropane cross-metathesis reaction generated a key (E)-alkene segment of the target molecule. IC50 determinations of (−)-CP2-disorazole C1 in human colon cancer cell lines indicated low nanomolar cytotoxic properties. Accordingly, this
抗有丝分裂天然产物 (-)-二索唑 C 1 的双环丙烷类似物的全合成分23 个步骤完成,总产率为 1.1%。乙烯基环丙烷交叉复分解反应生成了目标分子的关键 ( E )-烯烃链段。(-)-CP 2 -disorazole C 1在人结肠癌细胞系中的IC 50测定表明低纳摩尔细胞毒性特性。因此,这种合成生物电子等排体代表了第一种不含共轭二烯或多烯亚结构元素的生物活性二恶唑类似物。

The synthesis of a masked northern half of the natural product disorazole D1 and a cyclopropane analog of the masked northern half of disorazole A1 is described. The synthesis involves in both cases as key steps a Z-selective Wittig olefination and a Sonogashira cross-coupling reaction.

naturally occurring disorazole B1 molecule, a symmetrical totalsynthesis was devised with a monomeric advanced intermediate as the key building block, whose three-step conversion to the natural product allowed for an expeditious entry to this family of compounds. Application of the developed synthetic strategies and methods provided a series of designed analogues of disorazole B1, whose biological evaluation
