Abstract
A method of forming a sucrose-6-ester includes in sequence the steps of: a) contacting sucrose with a organotin-based acylation promoter in a solvent in the presence of a base selected from amines and basic alkali metal salts; b) removing water to form a tin-sucrose adduct; and c) contacting the tin-sucrose adduct with an acylating agent to form the sucrose-6-ester. The sucrose-6-ester may then be converted to sucralose.
