Process for the preparation of chlorosulfate and sulfamate derivatives of 2,3:4,5-bis-O-(1-methylethylidene)-beta-D-fructopyranose and (1-methylcyclohexyl)methanol. |
摘要 |
<p>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 .</p> |
