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 tasks when applied to appropriate substrates, such as the formation of sulfamidates from 1,2‐diols or epoxyalcohols, α‐ and β‐glycosylamines from carbohydrates, and cyclic sulfamides from 1,2‐aminoalcohols. Beyond delineating the power of these new reaction manifolds, we also describe the construction of a group of alternative Burgess‐type reagents that extends the scope of these new reactions even further.
