  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.

  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.

  我们设计并制备了一系列基于天然氨基酸支架的双功能膦硫脲有机催化剂。研究发现，L-苏氨酸衍生的双功能膦催化剂在促进丙烯酸酯与芳香醛的不对称莫里塔-贝利斯-希尔曼（MBH）反应方面非常有效，可以得到所需的 MBH 加合物，ee 值高达 90%。为了深入了解该反应的机理，我们研究了添加各种添加剂对 MBH 反应的影响。我们认为，催化剂的硫脲分子与烯醇中间体之间的氢键相互作用对反应的立体化学结果至关重要。本报告所述方法可为简单丙烯酸酯的对映选择性 MBH 反应提供实用的解决方案。

  A new type of chiral bifunctional phosphinothiourea derived from L-valine is synthesized and used as an organocatalyst in the enantioselective Monta-Baylis-Hillman reaction of aromatic aldehydes with acrylates. The desired products were obtained in good enantioselectivities (up to :33% ee) and in excellent yields (up to 96%) under mild reaction conditions. (C) 2009 Elsevier Ltd All rights reserved

  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
