A one-pot approach to the formation of N-substitutedsulfamatesfrom carboxylic acids using di-tert-butyl dicarbonate, tetrabutylammonium sulfamate, and pyridine under mild conditions is described. A reaction mechanism with two competing pathways is proposed; in reactions with aliphatic and electron-deficient aromatic acid substrates, the desired sulfamate products are formed, in contrast, symmetrical
