    摘要:
    The tryptamine derivative 1 readily reacted with methyl 4-acetyl-5-bromopent-4-enoate (9) that had been built up from 2,4-pentanedione. On intramolecular dehydration and subsequent [4 + 2] cycloaddition, the reaction product 10 gave the epimers 12 and 13 having the D-secoaspidospermane skeleton. Compound 12 directly and 13 after epimerization yielded (+/-)-3-oxominovincine (14). Regioselective reduction of 14 furnished (+)-minovincine (17).

  • Construction of novel spiroisoxazolines via intramolecular cyclization/methylation
    作者:Erick D. Ellis、Jianping Xu、Edward J. Valente、Ashton T. Hamme

    日期:2009.9
    Improved yields for the syntheses of a variety of spiroisoxazolines were achieved through intramolecular cyclization/methylation reactions of functionalized 5,5-disubstituted isoxazolines in one reaction vessel. Aromatic ring containing nitrile oxides and disubstituted geminal alkenes reacted in a 1,3-dipolar fashion to afford the corresponding 5,5-isoxazoline. A comparison of the relative location

    practicable synthesis of a pandoline-type alkaloid-like molecule is reported through an efficient preparation of carbinolamine ether intermediates (9a and 9b). The key step of the synthesis consists of an intramolecular cycloaddition of the secodine-type intermediate (2), which was formed from the tryptamine derivative (3) and lactol (4). The mechanism of the cycloaddition reaction was investigated by quantum
    通过有效制备甲醇胺醚中间体(9a和9b),报道了潘多林型生物碱样分子的可行合成。合成的关键步骤由secodine型中间(的分子内环化加成的2),其从所述的色胺衍生物(形成3)和乳醇(4)。通过量子化学计算研究了环加成反应的机理,发现它遵循涉及两性离子中间体的逐步机理(15)。通过采用这种策略,可以通过使色胺胺衍生物与适当官能化的醛反应来合成潘多林碱生物碱或类生物碱分子家族的其他成员。
