  • Mechanisms for Manganese(III) Oxidations with Alkenes
    作者:William E. Fristad、John R. Peterson、Andreas B. Ernst、Gordon B. Urbi
    DOI:10.1016/s0040-4020(01)87310-5
    日期:1986.1
    metal complexed organic radicals, and the importance of an oxo-centered manganese(III) triangle are discussed as they relate to the lactone annulation reaction. Single electron transfer oxidation of alkenes is described as a route toward 1,2-diacetates of alkenes within the 8.1-7.5 eV I.P. range. Three less common modes of Mn(III) reaction are discussed and compared with the two primary processes of
    乙酸(III)与羧酸和烯烃的反应中,已经鉴定出三个不同的过程,它们涉及烯烃和两个独立于烯烃的过程。通过产品研究,重排,稀释实验和文献动力学数据的组合,可以提出一个统一的机制图来描述这些过程。具体地,讨论了羧酸组分的α-H酸的作用,缺电子的自由基加成,属络合的有机自由基以及以氧代为中心的(III)三角形的重要性,因为它们与内酯环化反应有关。烯烃的单电子转移氧化被描述为通往8.1-7.5 eV IP范围内的烯烃1,2-二乙酸酯的途径。
  • Sonochemical switching from ionic to radical pathways in the reactions of styrene and trans-β-Methylstyrene with lead tetraacetate
    作者:Takashi Anto、Patrick Bauchat、André Foucaud、Mitsue Fujita、Takahide Kimura、Hajime Sohmiya
    DOI:10.1016/0040-4039(91)80174-5
    日期:1991.10
    The reactions of styrene and trans-β-methylstyrene with lead tetraacetate in acetic acid are greatly influenced by ultrasonic irradiation to give products resulting mostly from radical chain pathways, whereas mechanical agitation gives products only from ionic processes.
    苯乙烯和反式-β-甲基苯乙烯乙酸中的四乙酸铅的反应在很大程度上受到超声辐射的影响,从而产生的产物主要来自自由基链途径,而机械搅拌仅产生于离子过程。
  • γ-Butyrolactone aus metallierten enaminen
    作者:Burkard Costisella、Hans Gross、Hans Schick
    DOI:10.1016/s0040-4020(01)91101-9
    日期:1984.1
    Enamines of type 1 with anion-stabilizing substituents a are available by Horner-reaction of suitable phosphonates with aldehydes. Deprotonation of 1 gives aminoallyl anions 2, which react with carbonyl compounds (depending on a) either to butyrolactones 8 resp. 10 or to 6-membered lactons 13. This process amounts to synthesis of lactones from two carbonyl compounds and an α-aminosubstituted phosphonate
    具有阴离子稳定取代基α的1型烯胺可通过合适的膦酸酯与醛的霍纳反应获得。1的去质子化反应得到基烯丙基阴离子2,它与羰基化合物(取决于a)反应生成丁内酯8。10或6元内酯13。该过程相当于由两个羰基化合物和一个α-基取代的膦酸酯合成内酯。

    best choice for the bioreduction of ethyl 2-oxocyclohexylacetate 2e, which afforded cis-()-5e and trans-()-5e with 98 and 99% e.e., respectively. Reduction of 3-(2-oxocyclohexyl)propionic acid 3e with Pichia glucozyma gave predominantly the corresponding δ-lactone trans-()-6e with 94% e.e., whose absolute configuration was determined by means of CD spectroscopy.
