  手性伯胺/钯双催化用于β-酮羰基化合物与烯丙醇的不对称烯丙基烷基化

  摘要：

  开发了由手性伯胺和钯配合物组成的高效双催化体系，以促进β-酮羰基化合物的直接不对称烯丙基烷基化（AAA）。特别是，协同双催化系统使具有挑战性的无环脂肪族酮（例如β-酮羰基化合物和1,3-二酮）能够进行AAA反应。

• Asymmetric Retro-Claisen Reaction by Synergistic Chiral Primary Amine/Palladium Catalysis
  作者：Yanfang Han、Long Zhang、Sanzhong Luo

  日期：2019.9.20

  We described herein a chiral primary amine/palladium catalyzed asymmetric retro-Claisen reaction of β-diketones with salicylic carbonates. A series of chiral α-alkylated ketones and macrolides were obtained with good yields and excellent enantioselectivities upon a sequence of decarboxylative benzylation, retro-Claisen cleavage, and enamine protonation. This strategy features broad substrate scope

  我们在本文中描述了β-二酮与水杨酸盐碳酸酯的手性伯胺/钯催化的不对称逆克莱森反应。通过一系列脱羧苄基化，逆克莱森裂解和烯胺质子化反应，获得了一系列具有良好收率和优异对映选择性的手性α-烷基化酮和大环内酯。该策略具有广泛的底物范围，温和的条件以及以水杨酸碳酸酯为邻醌甲基化物前体的高原子经济性。

  We herein describe a synergistic chiral primary amine/achiral palladium catalyzed enantioselective terminal addition to allenes with α-branched β-ketocarbonyls and aldehydes. The reactions afford allylic adducts bearing acyclic all-carbon quaternary centers with high regio- and enantioselectivity. A wide range of allenes including those aliphatic or 1,1'-disubstituted could be employed, thus expanding
