  Transacetoacetylation with tert-butyl acetoacetate: synthetic applications

  摘要：

  Reaction of various nucleophiles with tert-butyl acetoacetate (t-BAA, 1a) is shown to be a convenient method for the preparation of a wide variety of acetoacetic acid derivatives. This material can be used to prepare acetoacetates and acetoacetamides from a wide variety of alcohols and amines. Reaction of 1a with an unhindered primary amine such as n-heptylamine under standard conditions gives unwanted byproducts due to the formation of the enamines 24 and 25. Formation of these byproducts can be minimized by dilution and/or altering the mode of addition.

• Ru(bpy)₃³⁺Electrochemiluminescence Detection of Aliphatic and Aromatic Amines with Diketene

  日期：2003.1

  A new derivatization method for the detection of aliphatic and aromatic amines, based on electro-chemiluminescence (ECL) with Ru(bpy)32+ is proposed. Sample amines were derivatized to acetoacetylamide-type derivatives using diketene. The derivatives were detected by reversed-phase HPLC with ECL detection using Ru(bpy)32+.

  提出了一种新的衍生化方法，用于基于电化学发光（ECL）与Ru(bpy)32+的脂肪族和芳香族胺的检测。样品中的胺类通过使用二酮酸酯衍生化为乙酰乙酰胺类衍生物。通过反相高效液相色谱（HPLC）结合Ru(bpy)32+的ECL检测对这些衍生物进行检测。
