  A new highly chemoselective isomerization of allylamides

  摘要：

  This work describes the first iridium-catalyzed isomerization of N-allylamides into enamides. This strategy allows the chemoselective preparation of (E)-N-(1-propenyl)-enamides and can be applied for the selective deprotection of N-allylamides. (C) 2004 Elsevier Ltd. All rights reserved.

• Chiral Photocages Based on Phthalimide Photochemistry
  作者：Alberto Soldevilla、Axel G. Griesbeck

  DOI：10.1021/ja066582n

  日期：2006.12.1

  class of photoremovable protecting groups, based on a photoinduced decarboxylation reaction coupled with the elimination of the caged molecule, is described for 2-phthalimido-3-hydroxy-propionate derivatives. When derived from enantiopure N-phthaloyl- serine or threonine, the chirality of the starting amino acid is transmitted to the protected (caged) molecule. These photocages possess good properties

  2-邻苯二甲酰亚胺-3-羟基-丙酸酯衍生物基于光诱导脱羧反应和笼状分子的消除，描述了一类新的可光去除保护基团。当衍生自对映体纯 N-邻苯二甲酰丝氨酸或苏氨酸时，起始氨基酸的手性传递到受保护的（笼状）分子。这些光笼具有用于生物系统的良好特性，手性的引入为研究非对映选择性光化学和涉及释放笼状分子的立体分化过程开辟了新的可能性。

  and convenient ruthenium(II) complex for the catalytic isomerization of O-allylethers, leading to thermodynamic-unfavored Z-product under mild conditions. The model substrate of allyl phenyl ether can be simply scaled up to 20 mmol to produce Z-product with TON of 2453 and TOF of 13,430 h−1 at 40–60 °C. The system of Ru(II)/Lewis Acid catalysts was suitable for various substituted O-allylethers and other

  在催化双键迁移反应中，通常以E-构型烯烃为主要产物，因为E-构型在热力学上是有利的。然而，由于结构-活性关系，有时在药物化学中需要Z-构型产物。在本文中，我们证明了一种新的策略，即路易斯酸促进了广泛使用且方便的钌（II）络合物用于O-烯丙基醚的催化异构化，导致在温和条件下产生热力学不利的Z产物。烯丙基苯基醚的模型底物可以简单地按比例放大至20 mmol以生产TON为2453，TOF为13,430 h -1的Z产物在40–60°C下。Ru（II）/路易斯酸催化剂体系适用于各种取代的O-烯丙基醚和其他类型的底物。通过包括动力学研究，配体抑制作用和分子光谱在内的机理研究，通过添加路易斯酸使PPh 3配体解离，以及由嵌合助剂形成五元Ru络合物均被认为是提高反应性和稳定性的必要步骤。通过金属氢化物加成消除机理控制催化双键迁移反应的立体选择性。这一新策略可能为生产用于药物化学的杂环化合物中热力学不利的产品提供新的机会。

  modes were detected for the N-phthaloyl derivatives of the aryl substituted amino acids phenylalanine, tyrosine, and dihydroxyphenylalanine (DOPA): (A) decarboxylation (only for (12a), (B) β-fragmentation, and (C) ring enlargement reaction. Processes B and C are initiated by photo electron transfer (PET), as the solvent dependence revealed. The DOPA derivatives 14a and 14b are the most prominent examples
