  The Heck–Matsuda arylation of 2-hetero-substituted acrylates

  摘要：

  The Heck-Matsuda arylation of 2-aza and 2-oxo-substituted acrylates is described. Several reaction conditions were evaluated including the influence of solvents, temperature, catalysts, and stoichiometry. While the oxygenated system was successfully arylated in benzonitrile with Pd-2(dba)(3) as catalyst, the aza-acrylate furnished methoxylated products. The methoxylated products were subjected to an elimination/reduction protocol to obtain the corresponding N,O-protected phenylalanine derivatives. A one-pot procedure for the preparation of phenylalanine derivatives from 2-aza-substituted acrylates is presented. (C) 2010 Elsevier Ltd. All rights reserved.

  electrophilic aromatic substitution reactions, known as tandem/domino/cascade reactions, have been reported for the construction of aromatic single skeletons, one of the most interesting and challenging possibilities remains the one-pot build-up of a complex aromatic molecule from multiple starting components, i.e., ultimately multi-component electrophilic aromatic substitution reactions. In this work, we show

  尽管已经报道了一些顺序的亲电芳族取代反应，称为串联/多米诺/级联反应，用于构建芳族单骨架，但最有趣和最具挑战性的可能性之一仍然是一锅积聚复杂的芳族分子。多个起始组件，即，最终实现多组分亲电芳族取代反应。在这项工作中，我们显示了如何调节氨基甲酸酯和酯类酚盐衍生物的离去基团能力提供了一种方法，该方法可以简单地通过改变温度在一个锅中以受控方式连续生成多个未掩盖的亲电试剂。在这里，我们演示了在一个锅中最多可自动形成三个键，以及由三组分亲电芳族取代反应产生的两个键的形成。该结果提供了我们的策略的概念证明，该策略适用于由多个简单分子自指导构建复杂芳香结构的过程，这可能是实现多组分亲电芳香取代反应的潜在途径。

  A series of chiral bisphosphine ligands were designed and synthesized based on single-handed quinoline oligoamide foldamers. The bisphosphine ligands can coordinate with Rh(cod)2BF4 in a 1 : 1 stoichiometry and the resulted chiral Rh(I) catalysts were applied in the asymmetric hydrogenation of α-dehydroamino acid esters, in which excellent conversions and promising levels of enantioselectivity were
