  Iodothyronine Deiodinase Mimics. Deiodination of o,o‘-Diiodophenols by Selenium and Tellurium Reagents

  摘要：

  To better understand, and in the extension mimic, the action of the three selenium-containing iodothyronine deiodinases, o,o'-diiodophenols were reacted under acidic conditions with sodium hydrogen telluride, benzenetellurol, sodium hydrogen selenide, or benzeneselenol and under basic conditions with the corresponding deprotonated reagents. Sodium hydrogen telluride was found to selectively remove one iodine from a variety of 4-substituted o,o'-diiodophenols, including a protected form of thyroxine (T-4) Thus, it mimics the D1 variety of the iodothyronine deiodinases. Sodium telluride was a more reactive deiodinating agent toward o,o'-diiodophenols, often causing removal of both halogens. Benzenetellurol and sodium benzenetellurolate sometimes showed useful selectivity for monodeiodination. However, the products were often contaminated by small amounts of organotellurium compounds. Sodium hydrogen selenide, sodium selenide, benzeneselenol, and sodium benzeneselenolate were essentially unreactive toward o,o'-diiodophenols. To gain more insight into thyroxine inner-ring deiodination, substituted 2,6-diiodophenyl methyl ethers were treated with some of the chalcogen reagents. Reactivity and selectivity for monodeiodination varied considerably depending on the substituents attached to the aromatic nucleus. In general, it was possible to find reagents that could bring about the selective mono- or dideiodination of these substrates.

  A highly crystalline iodinating reagent, [K·18-C-6]ICl2}n, was synthesized in high yield (93%). The trihalide is supported by an 18-crown-6 macrocycle and forms a coordination polymer in the solid state. This reagent iodinates anilines and phenols efficiently under mild conditions. Controlled mono-iodination with anilines was easily achieved while poly-iodination was observed with phenols.

  An oxidative procedure for the electrophilic iodination of phenols was developed by using iodosylbenzene as a nontoxic iodine(III)-based oxidant and ammonium iodide as a cheap iodine atom source. A totally controlled monoiodination was achieved by buffering the reaction medium with K3PO4. This protocol proceeds with short reaction times, at mild temperatures, in an open flask, and generally with high

  通过使用碘基苯作为无毒的碘（III）基氧化剂和碘化铵作为廉价的碘原子源，开发了一种用于亲电子碘化苯酚的氧化方法。通过用K 3 PO 4缓冲反应介质来实现完全受控的单碘化。在温和的温度下，在开放的烧瓶中，该方案以较短的反应时间进行，并且通常收率很高。用富电子和贫电子的酚以及杂环探索了革兰氏反应以及该方案的范围。量子化学计算显示，PhII（OH）·NH 3是最可能的碘化活性物质，呈反应性“ I +synthon。鉴于碘代芳烃部分的相关性，我们在本文中提出了实用，有效和简单的方法，其具有允许进入碘代芳烃核心单元的宽泛的官能团范围。

  3-Borylbenzynes were generated in situ from 6-boryl-2-iodophenyl trifluoromethanesulfonates using i-PrMgCl·LiCl and applied to Diels–Alder reactions with substituted furans and pyrroles. The reactions allowed good functional group compatibility and produced the cycloadducts in high yields with high distal selectivities. Effective conversion of the boryl group of the products was achieved. A series
