  Acyl transfers are key reactions in biology and in the laboratory. In biological systems they are involved in energy transport, in the assembly of complex molecules and in the mechanisms of efficient action of many hydrolytic enzymes. We report a mechanistic and calculational study of the selective N‐acylation reactions of amino acids by substituted aspirins, under mild conditions, in water at 25 °C

  酰基转移是生物学和实验室中的关键反应。在生物系统中，它们参与能量传输，复杂分子的组装以及许多水解酶的有效作用机制。我们报告了在温和条件下于25°C的水中通过取代的阿司匹林对氨基酸进行选择性N酰化反应的机理和计算研究。通过核磁共振鉴定反应的乙酰化氨基酸产物，并通过密度泛函理论研究反应步骤。版权所有©2012 John Wiley＆Sons，Ltd.

  novel structural units which have been explored as precursors in heterocyclic synthesis. The presence of two fluorine atoms at the β-position of the enamide moiety endows unique electrophilic reactivity. Treatment of these enamides with oxygen nucleophiles gives rise to a nucleophilic vinylic substitution (SNV) reaction, which was directed toward 2-fluoro-1,4-benzoxazines and 2-fluoro-1,4-benzoxazepin-5-ones
