  Organocatalytic Asymmetric Michael Addition of Aliphatic Aldehydes to Indolylnitroalkenes: Access to Contiguous Stereogenic Tryptamine Precursors

  摘要：

  Because of the importance of the indole framework and the versatile transformation of nitro and formyl groups, the efficient synthesis of optically pure 2-alkyl-3-(1H-indol-3-yl)-4-nitrobutanals, one type of tryptamine precursors are of great interest for pharmaceutical and biological research. Herein, the Michael addition of aliphatic aldehydes to indolylnitroalkenes has been developed using (S)-diphenylprolinol trimethylsilyl ether as an organocatalyst, which provides the desired optically pure syn 2-alkyl-3-(1H-indol-3-yl)-4-nitrobutanal derivatives in up to 98% yield with up to >99:1 dr and >99% ee. To show the synthetic usefulness of this methodology, optically active 2-alkyl-4-nitro-3-(1-tosyl-1H-indol-3-yl)butan-1-ol and tryptamine derivatives are readily obtained by stepwise systematic transformations.

  An operationally simple one-pot, three-component, diastereoselective synthesis of saturated carbazoles and related pyridazino[3,4-b]indoles, based on two sequential intermolecular pericyclic reactions, is described. The reaction sequence involves an intermolecular Diels–Alder (D–A) reaction of a 3-vinyl-1H-indole, containing an electron withdrawing N-protecting group, with a suitable dienophile. Due

  The installation of sulfonamide pharmacophores on heterobiaryls has successfully been executed by a previously unknown palladium-catalyzed intramolecular oxidative coupling in N-arylsulfonyl heterocycles followed by novel ring opening of heterobiaryl sultams with amine nucleophiles. The protocol has a wide scope of substrates warranting broad applications in the synthesis of heterobiaryls containing

• Structure function relationship study of yuehchukene. I. Anti-implantation and estrogenic activities of substituted yuehchukene derivatives

  (+/-)-Yuehchukene (YCK) is a novel bis-indole alkaloid with potent anti-implantation activity in rats. The present paper reports the activity of YCK derivatives by substitution on the parent compound. Substitutions on the indole nitrogens or on 2- and 5'- positions of the indole moiety abolished activity. N-1'-methylation of the free indole only permitted a 30% residual activity. Saturation of the C-9-C-10 cyclohexenyl double bond did not affect activity at all. Hydroxylation, whether on the C-9-C-10 double bond, or at C2 or C5, rendered the hydroxylated derivatives inactive. This suggests that the active metabolite in anti-implantation was probably not a hydroxylated derivative carrying estrogenic activity.

  (±)-Yuehchukene (YCK) 是一种具有强效抗着床活性的新型双吲哚生物碱。本文报告了YCK衍生物通过在母体化合物上进行的取代反应的活性。在吲哚的氮原子或吲哚基团的2-位和5'-位进行取代反应会使活性消失。仅对游离吲哚进行N-1'-甲基化处理，活性仅保持30%。饱和C-9-C-10环己烯基双键对活性没有任何影响。无论是对C-9-C-10双键、还是在C2或C5处进行羟基化处理，所得的羟基化衍生物均失去活性。这表明在抗着床活性的代谢产物中，很可能并非是具有雌激素活性的羟基化衍生物。

  We have developed an efficient synthesis of indole fused aminals with nucleophilic imines and indole-derived α,α-dicyanoolefins via N-sulfonyl group transfer. The combination of two privileged frameworks, tetrahydroisoquinoline or tetrahydro-β-carboline and indole, can be realized by this approach to the construction of aminals. The synthetic application of this method was further demonstrated by the
