Environmentally Benign Synthesis of Sugar Orthoesters Promoted by Anhydrous Sodium Acetate and Ultrasound

A convenient and alternative procedure for the synthesis of sugar orthoesters from glycosyl bromides with an- hydrous sodium acetate as base under ultrasound irradiation is described. Various sugar and sugar-sugar orthoesters were prepared in 70%-91% isolated yields.
