Abstract
The provided N-arylation method in water phase system for C-N coupling reaction comprises: using aryl halide and amine or nitrogen-contained heteroaromatic compound as material and water as solvent, heating traditionally or with microwave; using the carbonate, fluoride, phosphate and hydrate of alkali metal or alkali earth metal as base; with transient metal catalysis, adding surfactant to promote the C-N coupling reaction with acylated hydrazone compound as ligand. This invention just needs mild reaction condition, and has wide application.
Description
Technical field
The present invention relates to chemical field, especially a kind of method of N-arylation reaction.
Technical background
Arylamines is the important compound of a class, extensively is present in to have in the natural of physiologically active and the non-natural product, and the research that the C-N key is formed reaction causes that people pay attention to widely.
The Ullmann reaction of carbon-nitrogen cross-coupling was from existing so far history (Ley, the S.V. for a long time of reported first in 1903; Thomas, A.W.Angew.Chem.Int.Ed.2003,42,5400 reach relevant quoted passage).Because this reaction is normally in high boiling polar solvent, carry out under at the copper powder of high temperature, catalytic amount or equivalent as the condition of catalyzer, thereby there is long reaction time, the subsequent disposal difficulty of reaction, the not high drawback of reaction product complexity and reaction yield.Nineteen eighty-three, people such as Migita have found that the earliest the catalytic C-N key of Pd forms reaction (Kosugi, M.; Kameyama, M.; Migita, T.Chem.Lett.1983,927), 1994, Buchwald and Hartwig developed the catalytic C-N key of Pd simultaneously independently and have formed reaction ((a) Guram, A.S.; Buchwald, S.L.J.Am.Chem.Soc.1994,116,7901; (b) Paul, F.; Patt, J.; Hartwig, J.E.J.Am.Chem.Soc.1994,116,5969).Adopt the catalytic C-N key of Pd to form the more traditional Ullmann reaction of reaction and have condition gentleness relatively, reacting phase is to advantage such as simple, need to use high boiling organic solvent but also exist, toxicity is bigger, the price height, and to the shortcomings such as dependency of unstable and hypertoxic organophosphorus ligand, therefore, in recent years, the catalytic Ullmann of Cu reacts the very big development of having got back.People's such as Buckwald patent PCT/US02/12785 (WO02/085838) and Ley, S.V. and; Thomas, the summary of A.W. (Ley, S.V.; Thomas, A.W.Angew.Chem.Int.Ed.2003,42,5400) in introduced the formation method of the C-N key under the copper katalysis.By adding suitable part, use the Cu salt of catalytic amount, the Ullmann reaction can be carried out under comparatively gentle condition.Yet, no matter adopt which kind of metal catalyst, the N-arylation reaction of being reported in these documents is normally carried out in organic solvent.On the other hand, reaction takes the long application that has also seriously hindered high-throughput bioactivity screening in present medicine and the agricultural chemicals R﹠D process.Therefore, the objective requirement that to invent a kind of quick, eco-friendly reaction process be current such reaction will have good application prospects.
People such as Pell ó n have reported the catalytic C-N linked reaction of copper in the aqueous solution ((a) Pell ó n, R.F.; Carrasco, R.; Rod é s, L.Synth.Comm.1993,23 (10), 1447; (b) Pell ó n, R.F.; Est é vez-Braun, A.; Docampo, M.L.; Mart í n, A.; Ravelo, A.G.Synlett 2005, (10), 1606), have the aryl halides of carboxyl and the reaction of amine but only be confined to the ortho position.People such as Twieg reported cuprous iodide catalytic be synthetic method (Lu, the Z. of arylamines in the aqueous solution of part with the 2-dimethylaminoethanol; Twieg, R.J.Tetrahedron Lett.2005,46,2997), but only be confined to aromatic halogenate and amino acid or with certain water miscible short-chain fat amine is arranged and has the reaction of the aliphatic amide of hydroxyl.Reported the linked reaction of aromatic halogenate and ammoniacal liquor or short-chain alkyl amine in the catalytic aqueous solution of copper sulfate in the European patent EP 0549263.But above-mentioned reaction all can only be carried out at specific compound, thereby can not promote the use of.And people such as Buchwald have reported formation reaction (Huang, the X. of C-N key in the catalytic aqueous solution of Pd; Anderson, K.W.; Zim, D.; Jiang, L.; Klapars, A.; Buchwald, S.L.J.Am.Chem.Soc.2003,125,6653) there is defective because of the cost of its catalyst system.
