  Photochemical Protection of Amines with Cbz and Fmoc Groups

  摘要：

  The photochemical conversion of amines into carbamates was achieved using N-Cbz- N-Fmoc-, and N-Boc-5,7-dinitroindolines. This reaction allows the protection of amines in neutral medium. Primary and unhindered secondary amines were protected to yield their benzyloxycarbonyl- and 9-fluorenylmethoxycarbonyl derivatives efficiently, whereas bulky amines or anilines gave low yields or no product. On the other hand, the formation of N-Boc compounds, although possible, proceeded only with low yields.

  Representative examples of primary and secondary amines were protected as urea derivatives 4 of 5-bromo-7-nitro-indoline and even more efficiently as ureas 8 derived from 5,7-di-nitroindoline, via high-yield reactions with carbamoyl chlorides 3 and 7, respectively. Deprotection of 4 or 8 was achieved in high yields by UV irradiation at room temperature in Pyrex vessels under neutral conditions and

  伯胺和仲胺的代表性例子被保护为 5-溴-7-硝基二氢吲哚的脲衍生物 4，甚至更有效地作为衍生自 5,7-二硝基二氢吲哚的脲 8，通过与氨基甲酰氯 3 和7、分别。4 或 8 的脱保护是通过在室温下在 Pyrex 容器中在中性条件下和排除空气中进行紫外线照射来实现的。以类似的方式，二硝基二氢吲哚用作醇类和酚类的保护基团；衍生的氨基甲酸酯5和9同样可以以高产率光化学脱保护。
