    通过面包酵母介导的减少是在五个螺[4.5]癸烷-1,4-二酮衍生物进行4,9,12,15,和18。对映选择性一直很高,但这与面部非对映选择性无关,其范围从非常高到零。在某些情况下,酵母介导的还原反应的面部选择性低于NaBH 4。4的还原产物在几个步骤中转化为对映体富集的双环中间体5形式,用于合成角三喹烷戊烯1。酵母介导的螺酮21还原 证明了赤道羰基的还原是非常优选的反应方式。

  • Selective formation of angular tricyclic compounds by ruthenium-mediated ring-rearrangement metathesis
    作者:Fuye Gao、Craig T. M. Stamp、Paul D. Thornton、T. Stanley Cameron、Lauren E. Doyle、David O. Miller、D. Jean Burnell

    Unsaturated spirocyclic substrates bearing two alkenyl chains underwent ruthenium-mediated ring-rearrangement metathesis through relaying cyclohexene and cycloheptene moieties to give angularly fused tricyclics. In some instances where two products were expected, high degrees of selectivity were observed. In one instance the structural parameter leading to selectivity was very subtle; in others the transformation favoured the formation of products with a cis-fused cyclohexene moiety. An unusual transformation involving ring-opening, double-bond migration, and then ring-closing was observed.
    具有两个烯丙基链的不饱和螺环底物通过钌介导的环重排交叉反应,借助环己烯和环庚烯的中继形成了角度结合的三环化合物。在某些情况下,预期产物有两个,但观察到高选择性。在一种情况下,导致选择性的结构参数非常微妙;而在其他情况下,转化更倾向于形成具有顺式连接的环己烯部分的产物。观察到一种不寻常的转化过程,涉及开环、双键迁移,然后再闭环。
  • Facial selectivity in nucleophilic reactions of spirocyclic ketones can be controlled by a distant, orthogonal double bond
    作者:Pei-Ying Liu、D. Jean Burnell

    日期:——
    Spiro[4.5]dec-7-ene-1,4-dione and derivatives substituted at C-7, C-8, and/or C-9 gave products of reaction with methyllithium and with sodium borohydride that in every instance favoured nucleophilic carbonyl attack on the face syn to the double bond; the results are consistent with stereoelectronic control, and the selectivity correlates with a difference in the abilities of the orthogonal C–C bond to donate electron density.
    在C-7、C-8和/或C-9上被取代的螺[4.5]癸-7-烯-1,4-二酮及其衍生物与甲基锂和硼氢化钠反应,在每种情况下都倾向于对双键的同侧进行亲核羰基攻击;结果与立体电子控制一致,选择性与正交C-C键的供电子密度能力差异相关。
  • α-Methylenation/Diels-alder tandem reaction promoted by ammonium salts generated in situ from secondary–tertiary diamines and alkoxymethyl chlorides

    A simple one-pot synthesis of spiranones from cycloketones and dienes promoted by an ammonium salt generated in situ from diamine and alkoxymethyl chloride through a tandem alpha-methylenation/Diels-Alder reaction is described.

  • Enantio- and diastereoselectivity in the reduction of spiro[4.5]decane-1,4-dione derivatives with baker's yeast
    作者:Yan-Yi Zhu、D. Jean Burnell
    DOI:10.1016/0957-4166(96)00430-2
    日期:1996.11
    Reductions mediated by baker's yeast were carried out on five spiro[4.5]decane-1,4-dione derivatives 4, 9, 12, 15, and 18. Enantioselectivity was always very high, but this did not correlate with the facial diastereoselectivity, which ranged from very high to zero. In some instances, the facial selectivity of the yeast-mediated reduction was lower than that of NaBH4. The reduction product of 4 was
