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 |
摘要 |
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 solve nt selected from the group consisting of toluene, t-butyl methyl ether or tetrahydrofuran, and in the second step reacting of the resulting intermedia te with an amine in a solvent selected from the group consisting of toluene, t- butyl methyl ether, tetrahydrofuran and lower alkanol.
