技術(shù)領(lǐng)域
:本發(fā)明涉及一種由金屬銥絡(luò)合物催化的烯丙基碳酸酯和炔丙基親核試劑的不對稱烯丙基化反應(yīng)來制備重要的1,6-烯炔類化合物,該反應(yīng)可以高效率、高區(qū)域及對映選擇性地合成1,6-烯炔類化合物。
背景技術(shù)
:1,6-烯炔類化合物作為環(huán)和異構(gòu)化反應(yīng)中研究最廣泛的化合物之一,是一類非常重要的合成中間體。在過去的幾十年中,化學(xué)家以1,6-烯炔類化合物作為底物,報(bào)道了一系列重要的化學(xué)反應(yīng),并應(yīng)用于天然產(chǎn)物的全合成中。[(a)Ftirstner,A.;Davies,P.W.O^ot./抓2007,46,3410.(b)Lee,S.I.;Chatani,N.Ctew.Comonm.2009,371.]過渡金屬催化的不對稱烯丙基垸基化反應(yīng)是碳碳鍵形成的最為重要的反應(yīng)之一,在有機(jī)合成中占有重要的地位[(a)Trost,B.M.D.;VanVranken,L.C&肌1996,96,395.(b)Trost,B.M.爿cc.C/^附,及仏2002,35,695.(c)Trost,B.M.;Crawley,M.L.CTzew.iev,2003,,,2921.]。近年來,研究發(fā)現(xiàn)銥、鉬、鴇、銠等過渡金屬催化的烯丙基取代反應(yīng)有著自身的特點(diǎn),例如對于含末端烯烴的烯丙基底物可以高區(qū)域選擇性地生成支鏈產(chǎn)物。對于在金屬銥催化的烯丙基取代反應(yīng)的研究近年來也取得了許多進(jìn)展[(a)Helmchen,G.;Lipowsky,G.;Miller,N.C/ze肌2004,W,4595.(b)Hartwig,J.F.;Shu,C.Oe附,/抓£d2004,W,4794.(c)Hartwig,J.R;Leitner,A.;Shekhar,S.;Pouy,M.J./爿w.C/zem.&c.2005,"7,15506.(d)Hartwig,J.F.;Shekhar,S.;Trantow,B.;Leitner,A.J.jm.C/zew.Soc.2006,11770.]。但是使用含有炔烴的親核試劑在金屬催化的不對稱烯丙基取代反應(yīng)中還研究非常的少。我們發(fā)現(xiàn),使用銥絡(luò)合物催化下的不對稱烯丙基化基化反應(yīng),可以高區(qū)域和對映選擇性的合成1,6-烯炔類化合物。實(shí)現(xiàn)1,6-烯炔類化合物的高效不對稱合成,對此類化合物的應(yīng)用有著重要的意義。
