    (-)-Melodinine K 的合成:天然产物合成效率的案例研究。
    摘要:
    效率是现代天然产物合成的关键组织原则。实际标准包括时间、成本和合成目标所花费的精力,这些目标通过步数和规模进行跟踪。天然产物合成的执行,即其中使用的每个反应的总和和同一性,在一个极端上是化学(非生物)合成的连续统,然后是混合化学酶法,最后是生物(生物合成)其他,承认第一次综合属于自然。起始材料还跨越了结构复杂性的连续统一体,在一个极端接近目标的组成元素,其次是石油衍生和“手性池”构建块,以及复杂的天然产物(即半合成)。在此,我们详细介绍了实现 (-)-melodinine K(一种复杂的双吲哚生物碱)首次合成的方法。描述了使用我们的多米诺迈克尔/曼尼希环化的单体 (-)-tabersonine 和 (-)-16-甲氧基tabersonine 的全合成。从Voacanga Africana 中分离 (-)-tabersonine使用 tabersonine 16-羟化酶进行位点特异性 C-H

    latter compound was fed to cell suspension cultures of Catharanthus roseus were isolated and characterized. Two biotransformation products of tabersonine were isolated and shown to be lochnericine, which is formed by epoxidation of tabersonine at positions 14, 15, and lochnerinine, the 11-methoxylation product of lochnericine. The bioconversion ratio of the main biotransformation product, lochnericine,

    Intact living plants or plant parts are contacted with water to extract from the plant or plant part exuded chemical compounds, with the extracted chemical compounds subsequently being recovered from the water. The plant is treated with an elicitor or inducer to initiate or increase production of a chemical compound. The roots may be harvested for recovery of the chemical compounds. Valuable substances exuded from or onto a plant surface, such as a plant cuticle or the root of a plant, can be identified as biologically active. Libraries of substances exuded or secreted from various plant species can be elicited or induced to produce one or more of such substances.
