Process for the preparation of chlorosulfate and sulfamate derivatives of 2,3:4,5-bis-0-(1-methylethylidene)-beta-d-fructopyranose and (1-methylcyclohexyl)methanol

Abstract From the Canadian patent

A process for producing chlorosulfate and sulfamate esters of 2,3:4,5-bis-O-(1-methylethylidene)-.beta.-D-fructopyranose and (1-methylcyclohexyl)methanol is disclosed. The process involves a two step procedure involving in the first step reacting of an alcohol with sulfuryl chloride in the presence of a tertiary or heterocyclic amine base in a solvent selected from the group consisting of toluene t-butyl methyl ether or, tetrahydrofuran and in the second step reacting of the resulting intermediate with an amine in a solvent selected from the group consisting of toluene t-, butyl methyl ether, tetrahydrofuran and lower alkanol.
