    摘要:
    将环烷酮-2-羧酸酯与β-芳基乙胺加热,并对所得到的烯胺酯进行草酰化,随后经过路易斯酸催化的分子内环化反应,可以很好地获得多种红豆杉类杂环化合物。该方法不仅广泛适用于红豆杉类化合物的合成,还可用于A-去甲基和A-同源物以及红豆杉的环-D变体的合成。产品中的烷氧羰基团可以通过一种新的去羧基化方法(与氯化镁-二甲基亚硫酰胺的组合加热)轻松去除。因此,从2-乙氧羰基-4,4-乙烯基二氧环己酮出发,经过几步反应以高产率合成了2,8-二氧红豆杉派生物(35),并可以很容易地转化为天然红豆杉生物碱3-去甲氧基红豆杉啶酮。

  • Synthesis of Erythrina and Related Alkaloids. XXVI. Hydride Reduction of Erythrinan-7,8-diones and 7-O-Methanesulfonyl-8-oxo-erythrinans.

    The stereochemistry of hydride reduction of erythrinan-7, 8-diones was markedly affected by the bulkiness of the reagent and the polarity of the solvent : sodium borohydride in ethanol-tetrahydrofuran gave the 7β-hydroxy isomers and tetrabutylammounium borohydride in methanol gave the 7α-hydroxy isomers, stereoselectively. This can be explained in terms of fluctuation of the balance between product development control and approach control. The structures of the products were established by chemical and spectroscopic means. Their O-mesylates were hydrolyzed under basic conditions with epimerization to give a mixture of alcohols with a preference for the 7β-hydroxy derivatives. A similar epimerization of the mesyloxy group was also observed in lithium aluminum hydride reduction.
    硼氢化钠在乙醇-四氢呋喃中可生成 7β-羟基异构体,而四丁基铵硼氢化钠在甲醇中可生成 7α- 羟基异构体。这可以用产品开发控制和方法控制之间的平衡波动来解释。通过化学和光谱手段确定了产品的结构。它们的 O-甲磺酸盐在碱性条件下水解并发生外嵌合反应,生成一种醇类混合物,其中 7β- 羟基衍生物更受青睐。在氢化铝锂还原过程中,也观察到了类似的间羟基表聚现象。

    Heating of cycloalkanone-2-carboxylate with β-arylethylamine, and oxalylation of the resulting enamino-ester followed by Lewis acid-catalyzed intramolecular cyclization afforded various erythrinan-type heterocycles in excellent yields. This method is widely applicable not only to the synthesis of erythrinans but also to that of A-nor and A-homo analogs and ring-D variants of erythrinan. The alkoxycarbonyl group on the products was readily removed by a new decarbalkoxylation method (heating with magnesium chloride-dimethyl sulfoxide combination). Thus, starting from 2-ethoxycarbonyl-4, 4-ethylenedioxy-cyclohexanone, the 2, 8-dioxo-erythrinan derivative (35) was synthesized in several steps in high yield, and was readily converted to the natural Erythrina alkaloid, 3-demethoxyerythratidinone.
