  • SYNTHESIS IN THE FIELD OF THE ERYTHRINA ALKALOIDS: PART II. APPROACHES TO THE RING SYSTEM OF β-ERYTHROIDINE
    作者:B. Belleau
    DOI:10.1139/v57-095
    日期:1957.7.1
    The newly developed method for the elaboration of the ring system of the aromatic class of Erylhrina alkaloids has been successfully extended to the synthesis of 1,2,3,4-tetrahydroerythrinane (VI), a non-aromatic analogue. The key step in this synthesis involves ring closure of ketoamide (IV) itself, obtained from hexahydroindole and cyclohexenylacetic acid. Attempts to further extend this sequence
    新开发的用于合成 Eryhrina 生物碱芳香类环系的方法已成功扩展到 1,2,3,4-四氢赤藓烷 (VI),一种非芳香类似物的合成。该合成中的关键步骤涉及从六氢吲哚和环己烯基乙酸中获得的酮酰胺 (IV) 本身的闭环。尝试将该顺序进一步扩展到使用 2H-5,6-二氢吡喃乙酸作为起始材料在后者的制备阶段遇到了失败。对图 III 所示的一种新的且不相关的逐步方法进行了研究,但在最终步骤中失败了。还简要描述了其他不成功的方法。

    日期:2021.12.3
    A new dibrominated 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) is reported as a new metal-free photocatalyst. This BODIPY showed similar optoelectronic, electrochemical, and performance properties to those of Ru(bpy)3Cl2, one of the most common photocatalysts in a known radical–ionic transformation, such as the formation of 1,4-dicarbonyl compounds. Moreover, additional sequences in which the
    一种新的二溴化 4,4-二氟-4-bora-3a,4a- diaza - s - indacene (BODIPY) 被报道为一种新的无金属光催化剂。该 BODIPY 显示出与 Ru(bpy) 3 Cl 2相似的光电、电化学和性能特性,Ru(bpy) 3 Cl 2是已知自由基 - 离子转化(例如形成 1,4-二羰基化合物)中最常见的光催化剂之一。此外,使用这种 BODIPY 光催化剂开发了额外的序列,其中生成的氧离子被内部亲核试剂捕获。这些新序列允许直接制备 γ-烷氧基内酯、单保护的 1,4-酮醛和二氢呋喃。这种新的催化剂、方法和伪造的官能团可能是有机合成中的重要工具。
