  A traceless perfluorooctylsulfonyl tag for deoxygenation of phenols under microwave irradiation

  摘要：

  The perfluorooctylsulfonyl group is introduced as a traceless tag for solution-phase palladium-catalyzed deoxygenation reactions. The synthetic efficiency is improved by microwave irradiation for reaction and fluorous solid-phase extraction for separation. Further application of this traceless tag for multistep synthesis of substituted hydantoin and pyrimidine is also described. (C) 2004 Elsevier Ltd. All rights reserved.

• Transition-metal-free selective pyrimidines and pyridines formation from aromatic ketones, aldehydes and ammonium salts

  日期：——

  An efficient synthesis of pyrimidines and pyridines has been developed from readily available aromatic ketones, aldehydes and ammonium salts under transition-metal-free conditions. In this strategy, ammonium salts were used as nitrogen sources and only water was generated as a nontoxic byproduct. A catalytic amount of NaIO4 played an important role in the selectivity control, whereas substituted pyridines

  在无过渡金属的条件下，由容易获得的芳族酮，醛和铵盐已开发出嘧啶和吡啶的有效合成方法。在该策略中，铵盐用作氮源，仅水作为无毒副产物产生。催化量的NaIO 4在选择性控制中起重要作用，而在不存在吡啶的情况下主要形成取代的吡啶。

  A base-mediated three-component tandem reaction for the synthesis of multisubstituted pyrimidines from amidines, aryl alkynes, and aldehydes in a one-pot manner has been developed. Advantages of this transformation include being transition-metal-free, high efficiency, available starting materials, and being environmentally friendly.

  A ruthenium hydrido chloride complex (1) supported by a simple, heteroleptic bidentate P^N ligand (L1) containing a diarylphosphine and a benzannulated phenanthridine donor arm is reported. In the presence of base, complex 1 catalyzes multicomponent reactions using alcohol precursors to produce structurally diverse molecules including pyridines, quinolines, and pyrimidines via acceptorless dehydrogenative

  据报道，钌氢化氯络合物（1）由简单的杂二齿双齿P ^ N配体（L1）支撑，该配体包含二芳基膦和苯甲酰菲啶供体。在碱的存在下，配合物1催化使用醇前体的多组分反应，从而通过无受体脱氢偶联途径产生结构多样的分子，包括吡啶，喹啉和嘧啶。值得注意的是，L1不容易带有能够进行这类转化的过渡金属催化剂所共有的（去）质子化的布朗斯台德酸性或碱性基团，表明金属-配体的协同作用在该催化剂的催化反应性中不发挥重要作用1。一个η的一个罕见的例子2的钌-醛加合物，分离和结构表征，及其在acceptorless脱氢偶合反应的作用进行了讨论。
