A convenient synthesis of a variety of substituted N-hydroxysulfamides from chlorosulfonylisocyanate is reported. Alkyl groups can be introduced selectively on the N-Boc nitrogen of key intermediates 1a or 1b using the Mitsunobu reaction with alcohols. Subsequently the nitrogen carrying the silyloxy group can be alkylated under traditional conditions. Deprotection to the desired N-hydroxysulfamide
