一种脒类化合物及其制备方法
本发明涉及一类脒类化合物,尤其是含氟的脒类化合物,以及该类化合物的一种新型、简便、高效的制备方法。本发明提供一种在极温和条件下,由三组分原料出发,一锅合成具有各种取代基团的脒类化合物。本发明的化合物具有一些潜在的生理活性,为药物前体的筛选提供了一种极为有效的合成方法。
很多脒类化合物具有较好的生理活性(Matz,J.;McDonald,J.;Wu,E.Appl.WO 2000073313 Al 7 Dec 2000,75 pp.Gomes-Cardoso,L.;Echevarria,A.;Aguiar-Alves,F.;Jansen,A.M.;Leon,L.L.Microbios,1999,100,181-187.),因此它们在农药,医药上用途很广,如可用作消炎药,驱虫药,利尿药和治疗糖尿病及心血管疾病的药物(Greenhill,J.V.;Lue,P.Prog.Med.Chem.1992,30,203.)。近年来发现一些脒具有抗癌活性,并且有的已用作抗癌药(Gambar,R.;Nastmzzi,C.Biochem.Pharmacol.1994,47,599.)。脒类化合物作为有机合成的重要中间体,可用于合成含氮杂环化合物(Romero-Ortega,M.;Aviles,A.;Cruz,R.;Fuentes,A.;Gomez,R.M.;Plata,A.J.Org.Chem.,2000,65,7244-7247.Usui,H.;Watanable,Y.;Kanqo,M.J.Heterocycl.Chem.1993,30,551.)。而且脒具有较好的催化活性,可以很好的催化很多有机反应,也可用做环胺树脂和聚氨脂的固化剂(Aggarwal,V.K.;Mereu,A.J.Org.Chem.,2000,65,7211-7212.)。
随着脒的用途的进一步扩展,其合成方法的研究也引起了人们更多的重视(Choueiry,D.;Giraud,D.L.;Schotten,T.Patent Appl.WO 2000078725 A1 28 Dec2000,68 pp.Lange,U.E.W.;Schafer,B.;Baucke,D.;Buschmann,E.;Mack,H.Tetrahedron Lett.1999,40,7067-7070.)。脒类化合物的合成有两种常用的方法。第一种是Pinner synthesis方法,即在酸的作用下腈(nitriles)和醇反应生成中间产物amidates,然后在和胺发生交换反应而生成脒(Roger,R.;Neilson,D.G.Chem.Rev.1961,61,179.Tidwell,R.R.;Fox,L.L.;Geratz,J.D.Biochem.Biophys.Acta.1976,445,729.)。反应式如下:
Figure A0111319800041
第二种是由酰胺化合物(amides)在加热的条件下和POCl3、PCl5或SOCl2的作用,首先生成卤代亚胺产物(imidoyl chloride),然后再和胺反应而生成脒(Ogener,J.I.Acta.Pol.Pharm.1986,43,191.Dubina,V.L.et al Zh.Org.Khim.1986,22,2590.)。反应式如下:
非常明显以上两种方法各有其严重的局限性:1.它们都是两步反应,这样反应处理较为麻烦,而且产率因此受到限制;2.它们所用的试剂如酸、三氯氧磷、五氯化磷、二氯亚砜等,不但对反应底物要求具有较好稳定性,而且对反应设备要求较高,如耐腐蚀性等;3.对环境污染大,尤其是第二种方法要使用过量的含磷、含氯试剂,这会对环境造成极大的污染。在环保意识日益增强的今大,这种方法会逐渐受到限制。其它较为常用的方法用原甲酸酯法,酰胺缩醛法,硫醚氧化法,羧酸法等,但它们存在着同样的缺点。因此非常有必要发展一种高效的、低污染的、温和的合成方法。
最近Saluste报道了由异腈、芳基溴和二级胺在二价钯作用下甲苯中回流而实现了由三组分原料出发一步合成脒类化合物(Saluste,C.G.;Whity,R.J.;Furber,M.Angew.Chim.Int.Ed.2000,39,4156-4158.)。自1995年以来,多组分反应MCRs(Multicomponent Reactions)越来越受到人们的重视(Domling,A.;Ugi,I.Angew.Chem.Int.Engl.Ed.2001,39,3168-3210.)。MCRs与多步反应相比较可省去许多中间体的分离和纯化,因此它具有许多显而易见的优点,符合绿色化学(Green Chemistry)和原子经济性(Atom Economy)的观点,能够较好地符合理想的化学合成的要求(Ideal Chemical Synthesis)(Wender,P.A.;Handy,S.T.;Wright,D.L.Chem.Ind.1997,765.)。
本发明目的是提供一类脒类化合物,尤其是含氟的脒类化合物。
本发明另一目的是提供该类脒类化合物的合成方法。由三组分原料出发、不需外加化学反应试剂、室温下即可一步反应生成一系列的脒类化合物。
本发明的脒类化合物分子式为R1R2CHC(=NSO2Y)NR3R4,具有以下结构式:
其中R1或R2=H,、C1-5的烷基、取代或未取代的苯基ZPh-;
R3或R4=C1-5的烷基、取代或未取代的苯基ZPh-、-(C2H4C2H4)-、-(C2H4OC2H4)-、-(C2H4CH2C2H4)-、-(C2H4NHC2H4)-、-((C2H4N(CH3)C2H4))-、-((C2H4N(iC3H7)C2H4))-或-(C2H4NPhC2H4)-。
Y=C1-8的全氟烷基CnF2n+1,n=1-8;多氟烷基C2F4O(C2F4)mX,m=1-3;多氟取代的苯基C6FkH5-k,k=1-5;取代或未取代的苯基,ZPh-。
以上所述的取代基Z=H,C1-4的烷基或W;X是卤素,如F、Cl、Br、I;W是X、OR、NH2、NHR、NRR′、NO2,R或R′是C1-4的烷基。
本发明的上述脒类化合物可以通过下述方法制备;
在有机溶剂中和室温下,醛R1R2CHCHO、二级胺HNR3R4和叠氮化合物YSO2N3在室温反应进行完全2-48小时。在某些反应速度较慢的反应情况中,加入一定量的分子筛,不但可以增快该反应速度,而且还可以提高该反应的产率。该反应中上述化合物的摩尔比分别为醛∶二级胺∶叠氮=1~1.5∶1~1.5∶1.0。推荐摩尔比分别为醛∶二级胺∶叠氮=1~1.1∶1~1.1∶1.0。
采用本发明的方法,视底物的不同而反应时间略有差别,结果可以获得较好的产率67-95%。视底物的不同而反应产率略有差别,生成相应的脒类化合物R1R2CHC(=NSO2Y)NR3R4
对于产物是固体的反应情况下,其反应体系可经抽干除去溶剂即可。或者再经柱层析或重结晶即可得到纯品。
本发明的反应式如下所示:
该反应反应条件温和,不需加热或冷却;反应副产物仅是水和氮气,因此对环境无任何污染;该反应具有较高的原子经济性,不需要外加化学试剂;该反应原料易得而且具有极为广泛的可变种类,所以可以在短时间内合成大量的含有不同取代基团的脒类化合物。本发明的方法是一种适合工艺生产的方法。
通过下述实施例将有助于理解本发明,但并不限制本发明的内容。
