• Asymmetric Morita-Baylis-Hillman Reaction: Catalyst Development and Mechanistic Insights Based on Mass Spectrometric Back-Reaction Screening
  作者：Patrick G. Isenegger、Florian Bächle、Andreas Pfaltz

  Morita–Baylis–Hillman (MBH) reaction was developed. By mass spectrometric back‐reaction screening of quasi‐enantiomeric MBH products, an efficient bifunctional phosphine catalyst was identified that outperforms literature‐known catalysts in the MBH reaction of methyl acrylate with aldehydes. The close match between the selectivities measured for the forward and back reaction and kinetic measurements provided

  建立了评估不对称森田-贝利斯-希尔曼（MBH）反应催化剂的有效方案。通过对映异构体MBH产物的质谱反向反应筛选，发现一种有效的双功能膦催化剂在丙烯酸甲酯与醛类的MBH反应中性能优于文献中已知的催化剂。正反反应的选择性与动力学测量之间的紧密匹配提供了有力的证据，表明醛醇缩合步骤而不是随后的质子转移是速率和对映选择性的决定因素。

  A class of bifunctional phosphinothioureas derived from saccharide was developed as new organocatalysts for the enantioselective Morita‐Baylis‐Hillman reaction between acrylates and aldehydes. With 10 mol% of glucose‐based phosphinothiourea 1d, the allylic alcohols were obtained in up to 96% yield and 83% ee under mild reaction conditions.

  Novel (thio)urea–tertiary phosphines were developed for use as bifunctional organocatalysts readily available from naturally occurring molecules: saccharides and amino acids. The efficiency of the organocatalysts was demonstrated in the asymmetric Morita–Baylis–Hillman (MBH) reaction of aromatic aldehydes with acrylates. The MBH products were obtained in good yields (up to 85%) and with high enantioselectivities

• Enantioselective Morita–Baylis–Hillman reaction promoted by l-threonine-derived phosphine–thiourea catalysts

  A series of bifunctional phosphine–thiourea organic catalysts based on natural amino acid scaffolds were designed and prepared. L-Threonine-derived bifunctional phosphine catalysts were found to be very efficient in promoting asymmetric Morita–Baylis–Hillman (MBH) reaction of acrylates with aromatic aldehydes, affording the desired MBH adducts with up to 90% ee. To gain mechanistic insights into the reaction, the effects of adding various additives on the MBH reaction were investigated. We propose that the hydrogen bonding interactions between the thiourea moiety of the catalyst and the enolate intermediate are crucial for the stereochemical outcome of the reaction. The method described in this report may provide a practical solution to the enantioselective MBH reaction of simple acrylates.
