  Polymethylhydrosiloxane (PMHS)/trifluoroacetic acid (TFA): a novel system for reductive amination reactions

  摘要：

  Polymethylhydrosiloxine (PMHS)/trifluoroacetic acid (TFA) was discovered as a novel metal-free system for reductive amination reactions. A variety of(het)aryl amines as well as a representative carbamate and urea were successfully alkylated by benzaldehyde in the presence of PMHS and TFA in dichloromethane at room temperature in moderate to excellent yields (28-87%). Furthermore, this reaction protocol was Successfully applied to the alkylation of p-nitroaniline with a wide range of aldehydes, ketones, and a representative acetal to obtain the alkylated products in yields ranging from 40% to 92%. The current work represents one of the very few examples of PMHS being activated by a Bronsted acid. (C) 2009 Elsevier Ltd. All rights reserved.

  triacetoxyborohydride is presented as a general reducing agent for the reductive amination of aldehydes and ketones. Procedures for using this mild and selective reagent have been developed for a wide variety of substrates. The scope of the reaction includes aliphatic acyclic and cyclic ketones, aliphatic and aromatic aldehydes, and primary and secondary amines including a variety of weakly basic and

  存在三乙酰氧基硼氢化钠作为用于醛和酮的还原胺化的一般还原剂。已经开发了用于多种底物的使用这种温和选择性试剂的方法。反应范围包括脂族无环和环状酮，脂族和芳族醛，以及伯胺和仲胺，包括各种弱碱性和非碱性胺。局限性包括与芳族和不饱和酮以及一些位阻酮和胺的反应。1,2-二氯乙烷（DCE）是优选的反应溶剂，但是反应也可以在四氢呋喃（THF）中进行，有时也可以在乙腈中进行。乙酸可用作酮反应的催化剂，但醛类通常不需要。该过程可在对酸敏感的官能团（如乙缩醛和缩酮）的存在下有效地进行；它也可以在可还原的官能团如CC多键以及氰基和硝基的存在下进行。在DCE中，反应通常比在THF中更快，并且在两种溶剂中，在AcOH存在下反应都更快。与其他还原性胺化程序（如NaBH（3）CN / MeOH，硼烷-吡啶和催化氢化）相比，NaBH（OAc）（3）始终提供较高的收率和较少的副产物。在某些醛与伯胺发生二烷基化问题的还原胺化

  A base-promoted amination of aromatic halides has been developed using a limited amount of dimethylformamide (DMF) or amine as an amino source. Various aryl halides, including F, Cl, Br, and I, have been successfully aminated in good to excellent yields. Although the amination of aromatic halides with amines or DMF is usually considered as an aromatic nucleophilic substitution (SNAr) process, and the

  使用有限量的二甲基甲酰胺（DMF）或胺作为氨基源，已经开发出碱促进的芳香族卤化物胺化。包括F，Cl，Br和I在内的各种芳基卤化物均已成功地以良好或优异的收率胺化。尽管通常将胺或DMF芳香卤化物胺化视为芳香亲核取代（S NAr）过程，芳族卤化物的反应性为F> Cl> Br> I，发现该体系中芳族卤化物的反应性为I> Br≈F> Cl。该方案还显示了对多卤代芳烃的良好区域选择性。由于操作简单，氨基源和芳族卤化物的不受限制的可用性，无过渡金属的条件，不需要溶剂以及可扩展性，该协议对于工业应用很有价值。
