  Substrate Structural Effects in Yttrium(III)-Catalyzed Hydroamination/Cyclizations of 1,2-Disubstituted and 1,1,2-Trisubstituted Aminoalkenes ­Terminated by 2-(Phenyl) and 2-(2-Heteroarenyl) Groups

  摘要：

  A series of 2-phenyl- and 2-(2-heteroarenyl)-bearing amines possessing 1,2-disubstituted and 1,1,2-trisubststuted alkenes have been evaluated in intramolecular hydroaminations catalyzed by Y[N(TMS)(2)](3) (1(Y)). Aminoalkenes possessing a terminal 2-(5-trimethylsilyl)thienyl group exhibited substantially enhanced reactivity compared to their 2-(phenyl)-containing counterparts. Cyclization efficiencies imparted by the 2-[(5-trimethylsilyl) furanyl] substituent were comparable or only slightly better than those obtained with the simple the 2-(phenyl) group.

  Enantioselective hydroamination/cyclization of representative aminoalkenes catalyzed by chelating diamide complexes of La(III) and Y(III) are described. It is noteworthy that the La(III) complex derived from the sterically demanding ( R )- N , N ′-dibenzosuberyl-1,1′-binaphthyl-2,2′-diamine proligand provides enantioselectivities that are in many cases significantly higher than those obtained with

  描述了由螯合 La(III) 和 Y(III) 的二酰胺配合物催化的代表性氨基烯烃的对映选择性加氢胺化/环化。值得注意的是，由空间要求高的 (R)-N , N '-dibenzosuberyl-1,1'-binaphthyl-2,2'-diamine proligand 衍生的 La​​(III) 配合物提供的对映选择性在许多情况下显着高于那些用相应的 Y(III) 类似物获得的。此外，与 La(III) 对应物相比，LiCl 的存在通常会抑制 Y(III) 配合物获得的速率和对映选择性，此外还完全抑制 7b 的双环化。后一项研究中使用的酰胺配合物是通过使用新的高活性碱 La[N(TMS)(t-Bu)] 3 和 Y[N(TMS)( t-Bu)] 3 通过“胺消除”制备的。
