  Study of the stereoselectivity of the nucleophilic epoxidation of 3-hydroxy-2-methylene esters

  摘要：

  The diastereoselectivity of the nucleophilic epoxidation of 3-hydroxy-2-methylene esters has been studied. The 3-hydroxy-2-methylene esters were obtained through a Morita-Baylis-Hillman reaction. The resulting epoxyesters were treated with thiophenol for transformation into 2,3-dihydroxy-2-((phenylthio)methyl), which upon treatment with triphosgene afforded the corresponding cyclic carbonates.

• Asymmetric Morita-Baylis-Hillman Reaction: Catalyst Development and Mechanistic Insights Based on Mass Spectrometric Back-Reaction Screening

  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。

  The organocatalytic asymmetric allylic etherification reaction of Morita–Baylis–Hillman carbonates and silanols was reported for the first time. With modified cinchona alkaloid (DHQD)2PYR as the catalyst, a series of aromatic, heterocyclic, or aliphatic Morita–Baylis–Hillman carbonates (25 examples) worked well with triphenylsilanol, affording the corresponding products in moderate to good yields (up

  首次报道了森田-贝利斯-希尔曼碳酸盐和硅烷醇的有机催化不对称烯丙基醚化反应。以修饰的金鸡纳生物碱（DHQD）2 PYR为催化剂，一系列芳族，杂环或脂肪族Morita-Baylis-Hillman碳酸盐（25个实例）与三苯基硅烷醇效果很好，从而提供了中等至良好收率的相应产品（高达98 ％），高区域选择性（> 20：1）和良好的对映选择性（最高92％）。当使用二甲基苯基硅烷醇作为亲核试剂时，以60％的收率和87％的ee获得产物。

  Complementary chemistry! α‐Isocupreine (α‐ICPN) was synthesized for the first time in one step from quinine by treatment with CF3SO3H (see scheme). This compound serves as an enantiocomplementary catalyst to β‐isocupreidine (β‐ICD) in the Morita–Baylis–Hillman reaction.
