Description
Technical field
The present invention relates to a kind of polyfunctional group chiral phosphine compound, preparation method and the application in Rauhut-Currier reaction (RC reaction) that intersects between asymmetric molecult thereof.This compounds contains amide groups and phenolic hydroxyl group twoThe part of acid and the part of the Lewis alkali of a trivalent phosphine, it is possible to obtain the product of the most single intersection RC reaction with good yield and enantioselectivity.It it is the asymmetric version of the intermolecular intersection RC reaction of the first chiral phosphine catalysis of report at present.
Background technology
Rauhut-Currier reaction be 1963 by Rauhut and Currier report use tertiary phosphine catalysis construct carbon-carbon bond reaction (M.M.Rauhut, H.Currier, U.S.Patent, 1963,3074999;Chem.Abstr., 1963,58,11224a.).Due to the activity difference between different activated olefins so that course of reaction exists intersection RC reaction and the competition of molecule dimerization reaction, is at best able to obtain four kinds of different products.Owing to lacking, this reactive chemistry is the most effectively controlled so that this reaction application in organic synthesis by the biggest limited.2002, Roush and Krische achieves intramolecular RC reaction, be there is the group of large space steric hindrance by the electrical of two kinds of different alkene of regulation or introducing, reaction is made to be provided with good chemo-selective (S.A.Frank, D.J.Mergott, W.R.Roush, J.Am.Chem.Soc.2002,124,2404-2405;L.Wang, A.L.Lius, K.Agapiou, H.Y.Jang, M.J.Krische, J.Am.Chem.Soc.2002,124,2402-2403.).DBU afterwards, azepine Cabbeen, imidazoles/LiCl substitutes tertiary phosphine intersection RC between catalytic molecular used also as catalyst and reacts (J.R.Hwu, G.H.Hakimelahi, C.T.Chou, Tetra.Lett.1992,33,6469-6472;R.L.Atienza, K.A.Scheidt, Aust.J.Chem.2011,64,1158-1164;P.Shanbhag, P.R.Nareddy, M.Dadwal, S.M.Mobin, I.N.N.Namboothiri, Org.Biomol.Chem.2010,8,4867-4873;R.Kumar, T.Kumar, S.M.Mobin, I.N.N.Nambothiri, J.Org.Chem.2013,78,5073-5077;R.Zhou, J.Wang, J.Yu, Z.He, J.Org.Chem.2013,78,10596-10604.).Asymmetric research about RC reaction is confined to intramolecular mostly, the catalyst used has Cys (C.E.Aroyan, S.J.Miller, J.Am.Chem.Soc.2007,129,256-257.), diphenylprolinol silicon ether (E.Marqu é s-L ó pez, R.P.Herrera, T.Marks, W.C.Jacobs, D.R.M.de Figueiredo, M.Christmann, Org.Lett.2009,11,4116-4119.), chiral phosphine reagent (S.Takizawa, T.M.N.Nguyen, A.Grossmann, D.Enders, H.Sasai, Angew.Chem.2012,124,5519-5522;Angew.Chem.Int.Ed.2012,51,5423-5426;I) S.Takizawa, T.M.N.Nguyen, A.Grossmann, D.Enders, H.Sasai, Tetrahedron 2013,69,1202-1209.) and the little molecule organic catalyst (X.Zhang of other hydrogen bonds, M.Shi, Eur.J.Org.Chem.2012,6271-6279.).The connection olefin(e) acid ester using beta-schardinger dextrin catalysis of quick report is the most only executed for the research of intermolecular intersection RC reaction and the RC that intersects of maleimide reacts (Q.Zhao, C.Pei, X.Guan, M.Shi, Adv.Synth.Catal.2011,353,1973-1979.).And the intermolecular asymmetric research of the RC being catalyzed by the tertiary phosphine reaction for being originally found there is no report so far.
The research of the asymmetric reaction of difunctional organic catalyst catalysis in recent years gets more and more, and among these catalyst, amido (mainly with acid amides, thiocarbamide, side amine, urea, the form of dipeptides) and phenolic hydroxyl group are mainThe part of acid, optionally can control with the form realization of hydrogen bond in course of reaction (P.Chauhan, S.S.Chimni, Rsc Advances2012,2,737-758;A.Ting, J.M.Goss, N.T.McDougal, S.E.Schaus, Top.Curr.Chem.2009,291,201-232;X.Liu, L.Lin, X.Feng, Chem.Commun.2009,6145-6158.).But the research of polyfunctional group catalyst is the most few.Liu thinks that polyfunctional group catalyst can improve the speed (J.M.Gamier of the catalytic efficiency of catalyst, the selectivity of reaction and reaction in the way of polyfunctional group activation, C.Anstiss, F.Liu, Adv.Synth.Catal.2009,351,331-338).We using amide groups and phenolic hydroxyl group asThe part of acid, will be used for the trivalent phosphine the being catalyzed RC reaction part as Lewis alkali, has synthesized a kind of novel polyfunctional group chiral phosphine catalyst with natural amino acid for frame design, and this catalyst is successfully applied to intermolecular intersection RC reaction.
