    Enantiodivergence in the reduction of α-methyl and α-halomethyl enones by microorganisms
    摘要:
    Enones (Z)-3-methyl-(Z)-3-chloromethyl- and (Z)-3-bromomethyl-4-R-3-buten-2-one (R = n-pentyl, phenyl, 2'- and 4'-chlorophenyl, 3'- and 4'-nitrophenyl, 4'-methoxyphenyl) were synthesized and subjected to reduction by the microorganisms Saccharomyces cerevisiae and Geotrichum candidum. Whereas the bioreduction of 3-methy-4-R-3-buten-2-ones afforded the corresponding (S)-4-R-3-methybutan-2-ones, the bioreduction of 3-chloromethyl- and 3-bromomethyl-4-R-3-buten-2-ones afforded the corresponding (R)-4-R-3-methybutan-2-ones.

    氨基酸离子液体作为无溶剂 Morita-Baylis-Hillman 反应中的催化剂†
    摘要:
    在目前的工作中,我们描述了由铵盐作为阳离子、甘油衍生物和天然氨基酸作为阴离子形成的十种氨基酸离子液体 (AAIL) 的制备方法。均为粘稠油状物,无色或淡黄色,常温下有吸湿性。它们在许多质子和非质子极性溶剂中具有明显的溶解度。AAIL 在 Morita-Baylis-Hillman (MBH) 反应中用作催化剂。来自L-脯氨酸和L-组氨酸的离子液体衍生物证明了在无有机溶剂条件下在没有额外助催化剂的情况下催化甲基乙烯基酮和不同取代的芳香醛之间反应的能力。L-缬氨酸的 AAIL 衍生物, L-亮氨酸和L-酪氨酸仅在咪唑存在下催化MBH反应。MBH 加合物以中等至良好的产率获得。尽管 ILs 中的催化位点是对映体纯的形式,但所有的 MBH 加合物都是以它们的外消旋形式获得的。

  • 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。
  • Control of Chemo-, Regio-, and Enantioselectivity in Copper Hydride Reductions of Morita–Baylis–Hillman Adducts

    Nonracemically ligated copper hydride can be used to effect tandem SN2′/1,2-reductions of racemic Morita–Baylis–Hillman (MBH) acetates to access enantioenriched chiral allylic alcohols with defined olefin geometry. MBH esters, including those with β-substitution, can be transformed to stereodefined enoates by taking advantage of a bulky, oligomeric, in situ generated trialkoxysiloxane leaving group

    of polymer-supported Lewis bases such as PEG4600-(PPh2)2 and poly(DMAP) in the Baylis–Hillman reactions of N-tosylimines (ArCHNTs) 1 or the corresponding arenecarbaldehydes with α,β-unsaturated ketones has been investigated. The corresponding Baylis–Hillman adducts are obtained in good yields. The polymer-supported Lewis bases can be easily recovered by filtration and the Lewis base PEG4600-(PPh2)2

    In a rational chiral molecular design of chalcogenides, optically active thiepin with C2‐symmetric chirality was synthesized from commercially available thiophene. Then enatioselective Chalcogeno‐Baylis‐Hillman reactions of arylaldehydes with methyl vinyl ketone (MVK) and acrylates were investigated in the presence of thiepin‐Lewis acid complex. Finally, up to 64% ee was achieved in the presence of
