  Functional Primary Amines and Diamines from α-Aminoacids. A Concise Route to Substituted 2-Aminotetralins

  摘要：

  S-Phthalimidomethyl xanthates derived from various alpha-amino acids add efficiently to a range of unactivated alkenes to give a variety of highly functionalized, protected amines. In the case of phenylalanine and tyrosine derived xanthates, the adducts can be further converted into the rare 4-substituted 2-aminotetralines by a radical ring closure onto the aromatic ring.

  Decarboxylative functionalization via hydrogen atom transfer offers an attractive alternative to standard redox approaches to this important class of transformations. Herein, we report a direct decarboxylative functionalization of aliphatic carboxylic acids using N-xanthylamides. The unique reactivity of amidyl radicals in hydrogen atom transfer enables decarboxylative xanthylation under redox-neutral

  通过氢原子转移进行的脱羧功能化为此类重要转化的标准氧化还原方法提供了一种有吸引力的替代方法。在此，我们报告了使用 N-黄原酰胺对脂肪族羧酸进行直接脱羧功能化。酰胺基自由基在氢原子转移中的独特反应性使得在氧化还原中性条件下脱羧黄嘌呤化成为可能。该平台通过黄药组的后续阐述提供了对一系列衍生物的便利访问。
