背景技术
Strecker合成是醛-或酮-衍生的亚胺亲电试剂与氰化物生成α-氨基腈,并随后水解产生氨基酸或转变为其他化学和生物医学上有用的组成部分的一个化学族反应(“Advanced Organic Chemistry:PartB″,2nd Ed.F.A.Carey & R.J.Sundberg)。由于越来越多的药物显示出手性,不对称Strecker过程的研究变得越来越重要。同时,亚胺化学已经成为现在化学合成中最重要的以及最活跃的课题之一,特别是对于不对称催化(A.G.Doyle,E.N.Jacobsen,Chem.Rev.2007,107,5713-5743;E.Skucas,M.-Y.Ngai,V.Komanduri,M.J.Krische,Acc.Chem.Res.2007,40,1394-1401;S.F.Martin,Pure Appl Chem 2009,81,195-204;S.J.Cannon,Angew.Chem.Int.Ed.2008,47,1176-1178)。N-被保护的亚胺可以被用作许多不对称反应的亲电试剂和二烯亲和物(D.Enders,J.P.Shilvock,Chem.Soc.Rev.2000,29,359-373;R.M.Williams,A.J.Hendrix,Chem.Rev.1992,92,889-917;R.Bloch,Chem.Rev,1998,98,1407-1438;S.Kobayashi,H.Ishitani.Chem.Rev.1999,99,1069-1094)。在这些亚胺中,保护基已经被证明在一系列不对称合成过程中对于控制立体化学和化学选择性至关重要(S.J.Zuend,M.P.Coughlin,M.P.Lalonde,E.N.Jacobsen,Nature 2009,461,968-70;M.S.Sigman,P.Vachal,E.N.Jacobsen,Angew.Chem.Int.Ed.Engl.2000,39,1279 1281;S.C.Pan,B.List,Org.Lett.2007,9,1149-1151;J.J.Byrne,M.Chvarant,P.-Y.Chavant,Y.Vallee,TetrahedronLett.,2000,41,873-876)。用于一般有机和不对称合成的新型亚胺的发展已被需要。最近,各种N-被取代的,非手性N-磷酰叠氮化物,N-磷酰胺和N-磷酰亚胺已经被合成。由此产生的N-膦酰亚胺不仅可以用于Strecker反应,还可以用于许多其他的反应,例如不对称aza-Darzens反应(Kattuboina A.;Li,G.Tetrahedron Lett.2008,49,1573-1577),不对称aza-Henry反应(Kattuboina,A.;Kaur,P.;Ai,T.;Li,G.Chem.Biol.Drug Des.2008,71,216-223),不对称曼尼希反应(Mannich reaction)(a.Han,J.;Ai,T.;Li,G.Synthesis.2008,16,2519-2526;b.Han,J.;Ai,T.;Nguyen,T.;Li,G.Chem.Biol.Drug Des.2008,72,120-126;c.Han,J.;Chen,Z.;Ai,T.;Li,G.Chem.Biol.Drug Des.2009,73,203-208),烯丙基溴化镁的不对称加成反应(Kattuboina,A.;Kaur,P.;Nguyen,T.;Li,G.Tetrahedron lett.2008,49,3722-3724),Weinreb酰胺-和丙二酸衍生烯醇化物的不对称加成反应(a.Kaur,P.;Nguyen,T.;Li,G.Eur.J.Org.Chem.2009,912-916;b.Chen,Z.-X.;Teng,A.;Kaur,P.;L i,G.Tetrahedron Lett.,2009,50,1079-1081)以及芳基/烷基乙炔锂的不对称加成反应(Org.Biomol.Chem.,2010,8,1091-1096)。

N-膦酰基取代α-氨基腈合成的典型步骤
在干燥的玻璃瓶中,惰性气体保护下,加入无水甲苯,4分子筛和手性氨基酸。在加入异丙醇(1.0当量)之后,再加入二乙基铝氰化物(在甲苯中1.0M溶液)获得混浊的溶液。在室温中搅拌15分钟,溶液慢慢变成清澈。15分钟之后,加入预先溶解在3mL的甲苯中的手性N-膦酰亚胺(1.0当量),反应温度为-78℃再搅拌30分钟。该反应混合物用TLC不断监测,并允许搅拌5小时,之后加入10mL乙酸乙酯和10mL水,再加入0.05M盐酸,该反应混合物快速冷却。通过硅藻土过滤该溶液,分离有机层,并用无水硫酸钠干燥。过滤掉硫酸钠后,将有机层蒸发,得到浅黄色固体状的所需产品,其用正己烷洗涤后得到在所有实施例中报告的无需任何进一步纯化的白色固体状的纯产品。化合物12a:白色固体;产率(0.246g,92%);熔点112-114°C;[α]D
