  Oxidation von Methylpiperidin-Derivaten unter Berücksichtigung der Chiralität / Oxidation of Methylpiperidine Derivatives with Regard to Chirality

  摘要：

  当2-(2-甲基-1-哌啶基)乙醇衍生物3a和3b与Hg(II)-EDTA脱氢时，哌啶环的叔α-碳原子形成区域选择性的亚胺功能。这些中间体的环化产生了对映异构体混合物7a和7b的恶唑啉，通过NMR光谱学可以检测到溶液中的羟基烯胺物种8a/9a和8b/9b。来自7a的羟基烯胺可以通过与四嗪10的环加成反应捕获。恶唑啉的质子化生成了亚胺盐6a/6b・X，并失去了一个手性中心。为了防止2-(3-甲基-1-哌啶基)乙醇化合物中环的脱氢反应沿不同方向进行，第6位被两个甲基基团阻断。使用氨基醇17，实现了纯形式的一个对映异构体的分离，其脱氢反应生成了由NMR光谱学显示的立体异构体混合物18。2-(4-甲基-1-哌啶基)乙醇19与Hg(II)-EDTA反应产生对映异构体混合物21的比例为60:40。从对映体纯的苯基环氧烷获得了氨基醇R(-)-19和S(+)-19。在标准化条件下它们的脱氢反应总是显示出不能分离的异构内酰胺的广泛范围。

  Ruthenium(III) chloride-catalyzed efficient protocol for ethyl diazoacetate insertion into the N–H bond of secondary amines

  摘要：

  Ruthenium(III) chloride (1 mol%) alone can catalyze the insertion of ethyl diazoacetate into N-H bonds of various structurally and electronically diverse secondary cyclic amines under solvent-free conditions to afford the corresponding glycine esters in good yields under ambient conditions. Reactions with various aliphatic primary and aromatic amines examined, however, were unsuccessful.
