For exploring general routes to the pluramycin-class of antibiotics, including congeners with epoxide-bearing side chains, syntheses of kidamycinone and its epoxide (epoxykidamycinone) have been achieved. At the stage of the A-ring cyclization with alkene-bearing side chain, the desired 6-endo product was obtained as a major compound, although the corresponding undesired 5-exo product was also formed
为了探索通向普鲁霉素类抗生素(包括带有环氧化物侧链的同类物)的一般途径,已合成了Kidamycinone及其环氧化合物(epoxykidamycinone)。在带有含烯烃的侧链的A环环化阶段,虽然还形成了相应的不希望有的5-exo产物,但仍获得了作为主要化合物的期望的6-endo产物。
