The new 3-O-allyl ether derivatives of sugar were synthesized with high yield and mild reaction conditions. The synthesis of 3-O-acetylchloralose derivatives (5-8) and 3-O-allyl ether chloralose derivatives (9-12) were carried out. These new 3-O-allyl ether of chloralose derivatives are potential monomers for the synthesis of new glycopolymers.

Two hexoses and two pentoses have been reacted with two equivalents of trichloroacetaldehyde using boron trifluoride etherate as promoter in dioxane at reflux. The major products are exo-1,2-O-trichloroethylidenealdofuranoses in every case in varying yields, identical to the products previously obtained in lower yields using sulfuric acid or hydrochloric acid as promoter in trichloroacetaldehyde as
