This paper describes a formal total synthesis of the marine ladder toxin hemibrevetoxin B from Danishefsky's dienes. This approach couples the generation of C-glycosides from cyclic enol ethers with metathesis or acid-mediated annulation reactions. The result is a highly efficient synthesis of the tetracyclic ring system of hemibrevetoxin B.
本文描述了由Danishefsky的二烯正式合成的海洋梯状毒素半纤维素毒素B。这种方法将环烯醇醚的C-糖苷的生成与复分解或酸介导的环化反应结合在一起。结果是高效合成半短毒素B的四环系统。
