    KHMDS Enhanced SmI2-Mediated Reformatsky Type α-Cyanation
    摘要:
    A novel combination of SmI2, KHMDS, and TsCN can be utilized to introduce a cyano group into structurally diverse and highly sensitive 2-alkyl-chroman-4-ones. Subsequent oxidation allows the formed 2-alkyl-3-cyanochromones to be isolated in yields ranging from 49 to 77%. In addition, alpha-bromoketones and esters were found to undergo equally effective alpha-cyanation.

  • Boron-catalyzed dehydrative allylation of 1,3-diketones and β-ketone esters with 1,3-diarylallyl alcohols in water
    作者:Guo-Min Zhang、Hua Zhang、Bei Wang、Ji-Yu Wang
    DOI:10.1039/d1ra01922h
    日期:——
    environment friendly was developed. Allylic alcohols could be directly dehydrated in water by B(C6F5)3, without using any base additives. The reaction can afford the corresponding monoallylated product in moderate to high yield and has been performed on a gram-scale, and a quaternary carbon center can be constructed for the active methine compounds of 1,3-diketones or β-ketone esters in this process. The product
    开发了一种原子经济、绿色环保的无金属催化烯丙基化反应。烯丙醇可以直接在水中通过B(C 6 F 5 ) 3脱水,无需使用任何碱性添加剂。该反应能够以中等到高产率得到相应的单烯丙基化产物,并且已经在克级进行,并且在此过程中可以为1,3-二酮或β-酮酯的活性次甲基化合物构建季碳中心。产物可进一步转化,如合成四取代吡唑类化合物,或1,4-二烯和功能化二氢吡喃。

    DOI:10.1021/acs.joc.0c00568
    日期:2020.5.15
    The B(C6F5)3-catalyzed chemoselective hydrosilylation of α,β- and α,β,γ,δ-unsaturated ketones into the corresponding non-symmetric ketones in mild reaction conditions is developed. Nearly 55 substrates including those bearing reducible functional groups such as alkynyl, alkenyl, cyano, and aromatic heterocycles are chemoselectively hydrosilylated in good to excellent yields.
