Asymmetric first total synthesis of eudistomidins G, H, and I, tetrahydro-β-carboline alkaloids from the Okinawan marine tunicate Eudistoma glaucus, has been accomplished with the Bischler–Napieralski reaction and the Noyori catalytic asymmetric hydrogen-transfer reaction. The absolute configurations of eudistomidins G, H, and I were confirmed from comparison of the 1H and 13C NMR, and CD spectral
从冲绳海洋被膜Eudistoma glaucus的大黄素G,H和I,四氢-β-咔啉生物碱的不对称首次总合成已通过Bischler-Napieralski反应和Noyori催化不对称氢转移反应完成。通过比较1 H和13 C NMR以及合成和天然大戟素G,H和I的CD光谱数据,证实了大戟素G,H和I的绝对构型。
