Description
技术领域
本发明涉及一种多取代苯酚的制备方法。
背景技术
多取代苯酚在制药、农业化学品和高分子等领域有着重要作用,如2-羟基芳酮类、2-羟基苯甲酸类、2-羟基苯胺类、2-羟基磺酰胺类以及2-羟基苯甲醛类化合物(J.H.P.Tyman,Synthetic and Natural Phenols,Elsevier,New York,1996;Z.Rappoport,TheChemistry of Phenols,Wiley-VCH,Weinheim,2003;R.B.Bedford,S.J.Coles,M.B.Hursthouse,M.E.Limmert,Angew.Chem.2003,115,116;Angew.Chem.Int.Ed.2003,42,112;R.Dorta,A.Tongi,Chem.Commun.2003,760;T.A.Boebel,J.F.Hartwig,J.Am.Chem.Soc.2008,130,7534.)。这些化合物是杂环合成和药物合成的重要中间体。比如2-羟基芳酮可以用于合成苯并呋喃酮、苯并二氢吡喃-4-酮和苯并噁唑等多种含氧杂环,也可以用于心血管药物塞利洛尔、醋丁洛尔和普罗帕酮等多种药物的合成(M.Cabrera,M.Simoens,G.Falchi,M.L.Lavaggi,O.E.Piro,E.E.Castellano,A.Vidal,A.Azqueta,A.Monge,A.L.D.Cerain,G.Sagrera,G.Seoane,H.Cerecetto,M.Gonzalez,Bioorg.Med.Chem.2007,15,3356;J.W.Coe,M.G.Vetelino,J.Org.Chem.2003,68,9964;N.Barbero,R.SanMartin,E.Dominguez,Tetrahedron 2009,65,5729;M.Moure,R.SanMartin,E.Dominguez,Angew.Chem.2012,124,3274;Angew.Chem.Int.Ed.2012,51,3220;C.Chen,T.Andreani,H.Li,Org.Lett.2011,13,6300;H.Miyake,A.Nishimura,M.Yago,M.Sasaki,Chem.Lett.2007,36,332)。2-羟基苯胺衍生物和2-羟基芳酮是合成抗精神病药物洛沙平及其类似物二苯氧氮杂卓类(dibenzodiazepine)衍生物的重要中间体(D.Tsvelikhovsky,S.L.Buchwald,J.Am.Chem.Soc.2011,133,14228.Smits,R.1.;Herman,D.L.;Stegink,B.;Bakker,R.A.;Iwan J.P.de Esch;Leurs.R.J.Med.Chem.2006,49,4512)。2-羟基苯甲酸衍生物是合成治疗溃疡性结肠炎药物美沙拉嗪及其类似物的中间体(Neti,S.;Jaydeepkumar,L.Rasayan Journal of Chemistry,2009,2,688.)。
传统上合成多取代苯酚的方法包括有苄醇的氧化、卤代芳烃的水解、酯的Fries重排、苯甲醚类化合物的去甲基化等。这些方法往往具有一个或者几个缺点,比如产率低、选择性差等。
