syntheses of jadomycin A and the carbasugaranalogue of jadomycinB have been achieved in 6 and 20 longest linear steps, respectively. The key ring system of the aglycone was prepared by a 6π‐electron electrocyclic ring closure and subsequent hemiaminal ring closure. Acid sensitivity of the glycosidic bond in jadomycinB (see structure; X=O) precluded its synthesis but led to the carbasugaranalogue (X=CH2)
一个人的垃圾就是另一个人的宝:jadomycin A 和jadomycin B 的碳糖类似物的首次合成分别在 6 和 20 个最长的线性步骤中完成。苷元的关键环系统是通过 6π 电子电环闭合和随后的半胺环闭合制备的。jadomycin B 中糖苷键的酸敏感性(参见结构;X=O)阻止了它的合成,但导致了碳糖类似物(X=CH 2)。

A total synthesis of fenanthroviridone, gilvocarcin BE-12406X(2) antibiotic WS 5995B is described based on the palladium and copper catalyzed coupling reaction of sterically hindered aryl stannanes with a 2-bromonaphthoquinone. Copyright (C) 1996 Elsevier Science Ltd
