N-Methylimidazole catalyzes alcohol sulfamoylation using electron-deficient aryl sulfamates as activated group transfer reagents under mild conditions. The reaction provides intrinsic selectivity for 1° over 2° alcohols. The requisite aryl sulfamate donors are stable crystalline solids that can be readily prepared on a large scale.
