    Highly functionalized donor–acceptor cyclopropanes applied toward the synthesis of the Melodinus alkaloids
    摘要:
    A series of highly substituted vinylcyclopropanes were prepared and examined as reaction partners in a palladium-catalyzed (3+2) cycloaddition with nitrostyrenes. Described herein are our efforts to synthesize an elusive 1,1-divinylcyclopropane by several distinct approaches, and to apply surrogates of this fragment toward the synthesis of the Melodious alkaloids.

    有机铝试剂R2AlX(X=SPh,SeMe)能够以1,4-的方式容易地加成到α,β-不饱和羰基化合物上。生成的铝烯醇盐与醛反应,以较好至良好的产率得到醛醇加合物。通过形式上的HX消除反应,从加合物中可以得到α-取代的α,β-不饱和羰基化合物。整个转化过程相当于醛对1-酰基乙烯基负离子等价物的加成。二乙基铝碘也被发现是实现这种类型转化的有效试剂。

  • Divergent Amine-Catalyzed [4 + 2] Annulation of Morita–Baylis–Hillman Allylic Acetates with Electron-Deficient Alkenes

    + 2] annulation of Morita–Baylis–Hillman allylic acetates 2 with electron-deficient alkenes or diazenes has been developed for efficient syntheses of highly functionalized cyclohexenes, tetrahydropyridazines, and important spirocycles. This reaction unveils a new reactivity pattern of the intensely studied allylic compounds 2 acting as a C4 synthon in Lewis base catalyzed annulation reactions and also

  • Octanol-Accelerated Baylis-Hillman Reaction
    作者:Hyunah Choo、Youhoon Chong、Kwang-Su Park、Jinyoung Kim
    DOI:10.1055/s-2007-968032
    日期:2007.2
    The Baylis-Hillman reaction was greatly accelerated by use of octanol as an additive. Under the octanol-accelerated Baylis-Hillman conditions, unactivated aldehydes such as aliphatic aldehydes and aromatic aldehydes with electron-withdrawing substituents were readily converted into the desired products in good to high yields.
    使用辛醇作为添加剂,大大加速了Baylis-Hillman反应的进行。在加速的Baylis-Hillman条件下,未活化的醛类,如脂肪醛和含有吸电子取代基的芳香醛,都能在良好至高产率下轻易地转化为目标产物。
  • Baylis–Hillman reaction under solvent-free conditions — Remarkable rate acceleration and yield enhancement
    作者:Monmi Saikia、Jadab C. Sarma
    DOI:10.1139/v10-133
    日期:2010.12

    A simple and efficient method has been developed for remarkable rate acceleration and yield enhancement of the Baylis–Hillman reaction under solvent-free “neat conditions” and solvent-less isolation of products. Reaction of equimolar quantities of aldehyde and olefin in the presence of 20 mol% of DABCO under neat conditions affords the highest yield in most cases within the shortest reaction time, giving support to the mechanisms of proton transfer in protic and aprotic solvents. Solvent-free conditions are found to be especially fast, selective, and high yielding for aromatic aldehydes.

    为了在无溶剂的 "纯净条件 "下显著加快 Baylis-Hillman 反应的速率并提高产率,以及在无溶剂条件下分离产物,我们开发了一种简单而高效的方法。在 20 摩尔 DABCO 的存在下,等摩尔量的醛和烯烃在纯净条件下进行反应,在大多数情况下都能在最短的反应时间内获得最高的产率,为质子和非质子溶剂中的质子转移机制提供了支持。研究发现,在无溶剂条件下,芳香醛的反应尤其快速、选择性强且产率高。
  • Auto-tandem catalysis: facile synthesis of substituted alkylidenecyclohexanones by domino (4+2) cycloaddition–elimination reaction

    2-alkylidenecyclohexanone from 3-oxymethyl-2-siloxy-1,3-butadienes, which can be prepared from Baylis-Hillman adducts, and alpha,beta-unsaturated ketones is described. The process involves two mechanistically distinct reactions, (4+2) cycloaddition and elimination. Both of these reactions are catalyzed by Tf(2)NH.
