ABSTRACT Sucrose 6-acylates, key intermediates in the preparation of sucralose, can be prepared by subjecting a sucrose alkyl 4,6-orthoacylate to mild aqueous acidic hydrolysis to provide a mixture of sucrose 4- and 6- acylates and then treating the mixture with a base to convert the 4- acylate to the 6- acylate, The novel sucrose alkyl 4,6-orthoacylates are prepared by reacting sucrose in solution or suspension in an inert organic solvent with a trialkyl orthoacylate in the presence of an acid catalyst.
