The present invention relates to a method of converting an alcohol into a corresponding halide. This method comprises reacting the alcohol with an optionally substituted aromatic carboxylic acid halide in presence of an N-substituted formamide to replace a hydroxyl group of the alcohol by a halogen atom. The present invention also relates to a method of converting an alcohol into a corresponding substitution product. The second method comprises: (a) performing the method of the invention of converting an alcohol into the corresponding halide; and (b) reacting the corresponding halide with a nucleophile to convert the halide into the nucleophilic substitution product.

broadly applicable Fe‐catalyzed regioselectivealkoxyallylation of activated double bonds. Substituted allylic carbonates are converted into the corresponding σ‐enyl Fe complexes by reaction with Bu4N[Fe(CO)3(NO)] (TBAFe) at 30 °C. The liberated alkoxide adds to an activated double bond with the generation of a C‐nucleophile, which is trapped by the σ‐enyl Fe complex in a regioselective manner. Alternatively
我们在此介绍了一种多功能且广泛适用的活化双键的铁催化的区域选择性烷氧基烯丙基化反应。取代的烯丙基碳酸酯通过与Bu 4 N [Fe(CO)3(NO)](TBAFe)在30°C下反应转化为相应的σ-烯基Fe络合物。释放的醇盐会生成C-亲核试剂,从而形成一个活化的双键,该C-亲核试剂会以区域选择性的方式被σ-烯基Fe络合物捕获。或者,该醇盐在使经历迈克尔加成的外部前亲核试剂去质子化中用作碱。该方法的特点是宽泛的官能团耐受性,温和的反应条件,较低的催化剂载量和较高的区域选择性,有利于ipso取代产物。

The present disclosure relates to novel pyridine-containing macrocyclic compounds and libraries thereof that are useful as research tools for drug discovery efforts. This disclosure also relates to methods of preparing these compounds and libraries and methods of using these libraries, such as in high throughput screening. In particular, these libraries are useful for evaluation of bioactivity at existing and newly identified pharmacologically relevant targets, including G protein-coupled receptors, nuclear receptors, enzymes, ion channels, transporters, transcription factors, protein-protein interactions and nucleic acid-protein interactions. As such, these libraries can be applied to the search for new pharmaceutical agents for the treatment and prevention of a range of medical conditions.
