  • A General Approach Toward Bakkanes:  Short Synthesis of (±)-Bakkenolide-A (Fukinanolide)
    作者:D. Srinivasa Reddy
    DOI:10.1021/ol048726d
    日期:2004.9.1
    [reaction: see text] An efficient, general, and fully stereocontrolled approach to the family of bakkanes is disclosed. This route highlights a highly diastereoselective Diels-Alder/aldol sequence to furnish the common hydrindane precursor for the synthesis of bakkanes. The projected common intermediate was transformed to the (+/-)-bakkenolide-A in a short sequence.
    [反应:见正文]公开了一种有效的,通用的,完全立体声控制的bakkanes系列方法。该路线突出显示了高度非对映选择性的Diels-Alder / aldol序列,可提供常见的氢化茚前体,以合成巴卡因。所计划的共同中间体以短序列被转化为(+/-)-bakkenolide-A。

    and most characteristic pineapple-like odor was found for (5Z,7E,9)-decatrien-2-one. Global minimum energy calculation of the methyl ketones and the comparison to (1,3E,5Z)-undecatriene, a character impact compound of fresh pineapple, showed that a chain length of at least 10 carbon atoms and a terminal double bond embedded in a “L”-shaped conformation were common to compounds imparting an intense pineapple-like
    在农用工业支流上栽培食用菌Fetopsis betulina的过程中,感觉到令人强烈联想到菠萝的令人愉悦的味道。香精提取物稀释分析确定了两种具有明显菠萝味的风味成分。根据质谱数据,进行了(E)-戊-2,4-二烯-1-基三phosph溴化膦与乙酰丙酸乙酯的维蒂希反应。结果(5 E / Z,7 E,9)-癸三烯-2-酮与从真菌培养物中分离的化合物相同。合成了一些结构相关的甲基酮,经核磁共振和质谱法证实,并对其气味进行了表征。对于(5 Z,7 E,9)-十碳三烯-2-酮,发现最低的气味阈值和最典型的菠萝状气味。甲基酮的全球最小能量计算以及与(1,3 E,5 Z)-十一碳三烯(一种新鲜菠萝的特征冲击化合物)的比较表明,链长至少10个碳原子,并且末端嵌入了一个双键“ L”形构象是赋予强烈菠萝状气味的化合物所共有的。两者(5 E / Z,7 E,9)-癸三烯-2-酮尚未被描述为天然香料化合物。
