    使用由锆 (IV) 叔丁醇 (Zr(OtBu)4)、2 当量 (R)-6,6' 制备的新型手性锆催化剂,已成功进行甲硅烷基烯醇醚与醛亚胺的催化对映选择性曼尼希型反应-dibromo-1,1'-bi-2-naphthol ((R)-6,6'-Br2BINOL) 和 N-甲基咪唑。使用具有 N-取代羟基苯基部分的醛亚胺对于获得高选择性至关重要,并且 N-取代基团通过氧化裂解转化为游离胺。由芳香醛以及杂环醛和脂肪醛衍生的醛亚胺与甲硅烷基烯醇醚顺利反应,以高产率和高对映选择性得到相应的β-氨基酸衍生物。已经进行了几次 NMR 实验以阐明手性 Zr 催化剂的结构以及这种不对称反应的催化循环。最后,制备了一种新的BINOL衍生物,(R)-6,6'-双(三氟甲基)-1,1'-bi-2-萘酚((R)-6,6'-(CF3)2BINOL) . 原来是秀...

  • Remarkably Stable Chiral Zirconium Complexes for Asymmetric Mannich-Type Reactions
    作者:Kowichiro Saruhashi、Shū Kobayashi
    DOI:10.1021/ja062776r
    日期:2006.8.1
    Isolable, air-stable, storable, and highly selective chiral zirconium catalysts for asymmetric Mannich-type reactions have been developed. The reactions of imines with silicon enolates proceeded smoothly using 1-10 mol % of the powdered zirconium catalyst to afford the corresponding adducts in high yields with high stereoselectivities. The catalyst could be recovered and reused without significant
    已开发出用于不对称曼尼希型反应的可分离、空气稳定、可储存和高选择性手性锆催化剂。使用 1-10 mol% 的粉状锆催化剂,亚胺与硅烯醇化物的反应顺利进行,以高收率和高立体选择性提供相应的加合物。催化剂可以回收和再利用而不会显着损失活性。另一方面,获得了用于 X 射线分析的锆单晶,该晶体在不对称 Mannich 型反应中也表现出高性能。尽管这些锆催化剂的 NMR 分析显示在二氯甲烷中具有不同的结构,但表明不同催化剂形成了相同的关键中间体。
  • An air-stable chiral Hf-based catalyst for asymmetric Mannich-type reactions
    作者:Shū Kobayashi、Ryo Yazaki、Kazutaka Seki、Masaharu Ueno
    DOI:10.1016/j.tet.2007.05.115
    日期:2007.8
    A new class of isolable, air-stable, storable, and Hf-based catalyst has been developed. In the presence of 10 mol% of the powdered Hf catalyst, the asymmetric Mannich-type reactions of imines with silicon enolates derived from esters proceeded smoothly to afford the corresponding Mannich-type adducts in high yields with high enantioselectivities. Hafnium single crystals for X-ray analysis were obtained, and the crystals also showed high performance in the asymmetric Mannich-type reactions. (c) 2007 Published by Elsevier Ltd.
