  Chemoselective Esterification and Amidation of Carboxylic Acids with Imidazole Carbamates and Ureas

  摘要：

  Imidazole carbamates and ureas were found to be chemoselective esterification and amidation reagents. A wide variety of carboxylic acids were converted to their ester or amide analogues by a simple synthetic procedure in high yields

• Highly efficient and environmentally benign preparation of Weinreb amides in the biphasic system 2-MeTHF/water

  日期：——

  A straightforward chromatography-free preparation of Weinreb amides starting from acid halides has been achieved in the biphasic medium 2-MeTHF/water. Analytically pure compounds were isolated in excellent yields simply after removal of 2-MeTHF, which absolutely avoids the use of any contaminant organic solvent within the whole process due to its (practically) immiscibility with water.

  在 2-MeTHF/ 水的双相介质中，实现了从酸性卤化物开始的 Weinreb 酰胺的直接无色谱制备。由于 2-MeTHF 与水（实际上）不相溶，因此在整个制备过程中完全避免了使用任何污染性有机溶剂。

  The optimization, substrate scope, and mechanism of esterification and amidation of carboxylic acids mediated by imidazole-based reagents are discussed. The innate reactivity of carbonylimidazole reagents with a range of nucleophiles is also explored. New reagents developed for the synthesis of alpha,beta-unsaturated esters are described, as are reagents for the preparation of tertiary amides directly from carboxylic acids. (C) 2011 Elsevier Ltd.
