The first stereoselective total synthesis of new natural amide alkaloids 1–3 have been achieved from commercially available starting materials. Wittig olefination, Sharpless asymmetric dihydroxylation, epoxidation, a trans regioselective opening of 2,3-epoxy alcohol, Horner–Wadsworth–Emmons (HWE) olefination and amide coupling are the key steps. The amide alkaloids 1–3 are evaluated for their anticancer
的新的天然酰胺生物碱第一立体选择性全合成1 - 3已经从可商购的起始材料来实现的。Wittig烯烃化,Sharpless不对称二羟基化,环氧化,2,3-环氧醇的反式区域选择性开放,Horner-Wadsworth-Emmons(HWE)烯烃化和酰胺偶联是关键步骤。酰胺生物碱1 - 3用于抗结肠癌的人癌细胞系首次其抗癌活性(HT-29),乳腺癌(MCF-7)和肺(A-549)进行评价。
