Although the Burgess reagent (methoxycarbonylsulfamoyltriethylammonium hydroxide, inner salt) has found significant use in chemical synthesis as a dehydrating agent, almost no work has been directed towards its potential in other synthetic applications. As this article will detail, we have found that the Burgess reagent is remarkably effective at accomplishing a number of non-dehydrative synthetic
尽管Burgess试剂(甲氧基羰基氨磺酰基三乙铵氢氧化物,内盐)已发现在化学合成中作为脱水剂具有重要用途,但几乎没有工作针对其在其他合成应用中的潜力。正如本文将要详细介绍的那样,我们发现,将Burgess试剂应用于适当的底物上,例如从1,2-二醇或环氧醇,α-和C-形成氨基磺酸盐时,在完成许多非脱水合成任务方面非常有效。来自碳水化合物的β-糖胺和来自1,2-氨基醇的环状磺酰胺 除了描述这些新反应歧管的功能之外,我们还描述了一组替代的Burgess型试剂的构造,这些试剂进一步扩展了这些新反应的范围。
