  Morita-Baylis-Hillman 酮的酰基转移驱动的 Rauhut-Currier 二聚化

  摘要：

  在 DABCO 存在的情况下，观察到源自 Morita-Baylis-Hillman 加合物的 1,1-二取代活化烯烃的偶然 Rauhut-Currier 二聚反应。该反应由酰基的迁移驱动，并在大多数情况下产生多官能化的烯醇酯，产率大于 90%，无需柱层析纯化。酰基转移被认为是通过典型的 Morita-Baylis-Hillman (MBH) 反应的过渡态进行的，并得到涉及计算计算的简短机理研究的支持。

  A high-yielding and enantioselective access to novel N-Boc terminal aziridines, bearing a quaternary stereogenic center, has been developed via an aza-Michael initiated ring-closure (aza-MIRC) reaction of α-acyl acrylates with an N-tosyloxy tert-butyl carbamate catalyzed by a chiral amino thiourea. The feasibility of the aziridine regioselective ring-opening to valuable α,α-disubstituted α-amino acid

  A highly chemoselective phosphine-catalyzed Rauhut–Currier reaction between maleimides and enones has been realized under very mild conditions, affording the corresponding cross-coupling products in moderate to excellent yields. On the basis of this reaction, an efficient dual phosphine-mediated one-pot synthesis of bicyclic and polycyclic compounds containing a cyclopenta[c]pyrrole skeleton has been

  在非常温和的条件下已实现了高度化学选择性的膦催化的马来酰亚胺和烯酮之间的Rauhut-Currier反应，从而以中等至极好的收率提供了相应的交叉偶联产物。在此反应的基础上，据此开发了一种有效的双膦介导的一锅合成含环戊五烯[ c ]吡咯骨架的双环和多环化合物的方法，其特征是分子间Rauhut-Currier反应和分子内Wittig反应的串联序列。

  日期：2022.1

  A diethyl phosphite mediated reductive [1 + 4] annulation of α-ketoesters with α, β-unsaturated ketones has been developed, which provides an effective and simple method to prepare polysubstituted 2,3-dihydrofurans bearing a quaternary carbon center in fair to excellent yields. In the reaction, the in situ generated [1,2]-phospha-Brook rearrangement adduct of phosphite and α-ketoester presumably serves

  of Morita–Baylis–Hillman ketones with 2-aminothiophenol mediated by Cs2CO3 results in an oxidative cyclization to 2,2-disubstituted dihydro-1,4-benzothiazines, with the structure of the product indicating the occurrence of an aza-Michael addition along the pathway. In contrast, in the absence of a base, the parent compounds interact to produce a thia-Michael adduct instead. A deeper mechanistic study

  Morita-Baylis-Hillman 酮与 2-氨基苯硫酚在 Cs 2 CO 3介导下的反应导致氧化环化为 2,2-二取代的二氢-1,4-苯并噻嗪，产物的结构表明氮杂的发生-迈克尔沿着路径添加。相反，在不存在碱的情况下，母体化合物相互作用产生硫杂-迈克尔加合物。更深入的机制研究提高了我们对明显矛盾的理解，并提供了对反应性依赖于碱基的转换的见解。
• Catalyst-Free Conjugate Addition of Indolizines to <i>In Situ</i>-Generated Oxidized Morita–Baylis–Hillman Adducts
  作者：Thiago S. Silva、Lucas A. Zeoly、Fernando Coelho

  DOI：10.1021/acs.joc.0c00189

  日期：2020.4.17

  Sequential one-pot 2-iodoxybenzoic acid (IBX) oxidation of Morita-Baylis-Hillman (MBH) adducts followed by catalyst-free indolizine conjugate addition was developed. The wide scopes of MBH adducts and indolizines were investigated, and densely functionalized adducts were obtained in yields of up to 94%. The conjugate addition step occurred in less than a minute at room temperature with total regioselectivity toward indolizine C3 carbon. Less nucleophilic C1 carbon was also alkylated when C3-substituted indolizines were employed as the substrate.
