    A novel and efficient approach to highly substituted indolizines via 5-endo-trig iodocyclization
    摘要:
    A new approach to indolizines has been developed using a 5-endo-trig iodocyclization of allylic esters followed by isomerization and dehydroiodination facilitated by triethylamine at rt This mild procedure enabled us to synthesize a number of highly substituted indolizines in good yields.

  • Ru-Catalyzed Completely Deoxygenative Coupling of 2-Arylethanols through Base-Induced Net Decarbonylation
    作者:Seetharaman Manojveer、Sebastian J. K. Forrest、Magnus T. Johnson
    DOI:10.1002/chem.201705208
    日期:2018.1.19
    Substituted arylethanols can be coupled by using a readily available Ru catalyst in a fully deoxygenative manner to produce hydrocarbon chains in one step. Control experiments indicate that the first deoxygenation occurs through an aldol condensation, whereas the second occurs through a base‐induced net decarbonylation. This double deoxygenation enables further development in the use of alcohols as
    可以通过使用容易获得的Ru催化剂以完全脱氧的方式偶联取代的芳基乙醇,从而一步生成烃链。对照实验表明,第一次脱氧通过羟醛缩合发生,而第二次通过碱诱导的净脱羰发生。这种双重脱氧使得在将醇用作通用和绿色烷基化试剂以及其他领域(例如脱氧和过度官能化的生物质的提质以生产烃)中的进一步开发成为可能。

    acidity of [2][OTf] was exploited in the catalytic reductive coupling of a variety of aldehydes into symmetric ethers of type L in good to excellent yields under mild conditions using Et3SiH as the reductant. Additionally, [2][OTf] was found to selectively catalyze the Aldol condensation reaction to afford α-β unsaturated aldehydes (M) when aldehydes with 2 α-hydrogen atoms were used. Finally, [2][OTf]

    作者:Laura Chapado、Pablo Linares-Palomino、Concepción Badía、Sofía Salido、Manuel Nogueras、Adolfo Sánchez、Joaquín Altarejos
    DOI:10.3390/molecules14082780
    日期:——
    Five new bulky moiety-modified analogues of the sandalwood odorant Polysantol® have been synthesized by aldol condensation of appropriate aldehydes with butanone, deconjugative α-methylation of the resulting α,β-unsaturated ketones, and reduction of the corresponding β,γ-unsaturated ketones. The final compounds were evaluated organoleptically and one of them seemed to be of special interest for its natural sandalwood scent.

  • Solvent-free organic reactions on silica gel supports. Facile transformation of epoxides to β-halohydrins with lithium halides
    作者:Hiyoshizo Kotsuki、Tomoyasu Shimanouchi、Reiji Ohshima、Shunsuke Fujiwara
    DOI:10.1016/s0040-4020(98)83007-x
    日期:1998.3
    The reaction of epoxides with lithium halides was efficiently promoted on the surface of silica gel in the absence of any solvent to give the corresponding β-halohydrins. The reactivity of lithium halides was shown to follow the order LiI> LiBr>> LiCl, and the reactivity of LiCl was dramatically increased by adding an equivalent amount of water to this system. On the other hand, a similar reaction
    在不存在任何溶剂的情况下,可在硅胶表面上有效地促进环氧化物与卤化锂的反应,得到相应的β-卤代醇。卤化锂的反应性显示为遵循LiI> LiBr >> LiCl的顺序,并且通过向该系统中添加等量的水,大大提高了LiCl的反应性。另一方面,与α,β-环氧酮的类似反应产生α-卤代烯酮衍生物,大概是通过卤代醇中间体。还研究了(R)-(+)-苯乙烯氧化物的环氧化物开放反应,以阐明该反应的立体化学特征。
  • A selective solvent-free self-condensation of carbonyl compounds utilizing microwave irradiation
    作者:Lalit Kumar Sharma、Kyung Bo Kim、Gregory I. Elliott
    DOI:10.1039/c1gc15164a
    日期:——
    An environmentally benign microwave-assisted solvent-free self-condensation of carbonyl compounds was developed using catalytic amounts of triethylamine and lithium perchlorate. Changing the amount of lithium perchlorate helps in controlling the ratio of the single-condensation and double-condensation products. The effect of other additives and microwave activation was also investigated. The optimized conditions were then applied to various cyclic/acyclic ketones and aldehydes, with selectivity observed in many cases.
