  • Alkoxide-catalyzed ring expansion of 1,3-cyclobutanediones with aldehydes
    作者:Mizuki Yamazaki、Tomoyuki Yoshimura、Jun-ichi Matsuo
    DOI:10.1016/j.tetlet.2020.151804
    日期:2021.2
    1,3-Cyclobutanediones (dialkyl ketene dimer) reacted with various aromatic aldehydes to give six-membered cyclic β-keto esters by using a catalytic amount of potassium ethoxide. Effects of alkoxide catalysts and spiro cyclic groups at the 2,4-positions of 1,3-cyclobutanediones were investigated.

  • Photofragmentation reactions of dithiolactones
    作者:Kayambu Muthuramu、Bhagavathi Sundari、Vaidhyanathan Ramamurthy

    日期:1983.1
    The occurrence of Norrish type-I α-cleavage has been established in β-dithiolactones, involving the n-π* singlet state (diradical and carbene reactive intermediates). Concerted ring expansion to a thiacarbene from the excited state is suggested to be responsible for the formation, at least in part, of one of the cyclic thioacetals. Although this α-cleavage process is similar to that of corresponding
    已经确定了β-二硫内酯中涉及n-π*单线态(双自由基和卡宾反应性中间体)的诺里斯-I型α-断裂的发生。据建议,从激发态起一致地扩环成噻卡宾是至少部分地形成环状硫缩醛之一的原因。尽管该α-裂解过程与相应的β-内酯类似,但所得中间体的行为却不同。
  • Effect of Spiro Ring Size on the Photochemical Ring Expansion of Dispiro Substituted Cyclobutane-1,3-diones
    作者:Koji Kimura、Masakazu Takamura、Shigeru Koshibe、Masayoshi Juro、Yoshihiro Fukuda、Yoshinobu Odaira
    DOI:10.1246/bcsj.49.741
    日期:1976.3
    The photochemical ring expansion of dispiro substituted cyclobutane-1,3-diones in methanol has been investigated. The formation of ring expansion product was strongly dependent on the spiro ring size of dispiro substituent. The ring expanded acetal was obtained in a low yield when the spiro ring of dispiro substituted cyclobutane-1,3-diones was a five- or seven-membered ring. This is the first example
    研究了二螺取代的环丁烷-1,3-二酮在甲醇中的光化学扩环。扩环产物的形成强烈依赖于二螺取代基的螺环尺寸。当双螺取代的环丁烷-1,3-二酮的螺环为五元环或七元环时,扩环缩醛的收率较低。这是环丁烷-1,3-二酮光化学扩环的第一个例子。假设了一种机制。
  • Ring strain release as a strategy to enable the singlet state photodecarbonylation of crystalline 1,4-cyclobutanediones
    作者:Gregory Kuzmanich、Miguel A. Garcia-Garibay
    DOI:10.1002/poc.1902
    日期:2011.10
    is essential to slow down the combination of the intermediate acyl–alkyl biradical back to the starting ketone. Relatively long triplet acyl–alkyl biradical lifetimes give a chance for the loss of CO to occur. Looking for additional strategies to generate transient biradicals in solids, we studied the solid state photochemistry of four aliphatic, dispiro‐substituted 1,4‐cyclobutandiones (1a–d) that
    挑战大多数化学家的直觉,利用环状酮的光脱羰基化可以在固态下可靠地生成高反应性的二烷基双自由基。但是,已经表明,在前体的α-碳上具有共振解离能力的自由基稳定基团是促进α裂解反应所必需的,并且三重态反应性对于减慢中间酰基的结合是必不可少的。烷基双自由基回到起始酮。相对较长的三重态酰基-烷基双自由基寿命为发生CO损失提供了机会。为了寻找在固体中生成瞬态双基的其他策略,我们研究了预期从单线态反应的四种脂族,双螺取代的1,4-环丁二酮(1a–d)的固态光化学。我们假设小环羰基释放出环应变将使反向酰基-烷基组合不利,从而使CO的损失得以有效且不可逆地发生。我们在这里报告在溶液,块状(粉末)晶体和纳米晶体光化学中进行的研究结果。我们最近表明,对二螺环己基-1,3-环丁二酮1c的激发导致中间羟基烯丙基的捕获,其半衰期约为42分钟。我们对其他三种结晶衍生物的研究表明,尽管它们均能有效反应,但羟烯丙基的超长寿
