To provide processes for producing alkylamino glucosaminide phosphate compounds and disaccharide compounds functioning as immunoeffectors or adjuvants intended for vaccines and the like comprising various novel intermediates and intermediate steps.
A method for producing a glycosyl halide is provided which comprises the step of reacting an O-silyl glycoside with an α, α-dihalomethyl alkyl ether in the presence of an about stoichiometric or excess amount, in relation to the silyl glycoside, of an element selected from the group consisting of zinc chloride, zinc bromide, and boron trifluoride. Further, a method for producing a disaccharide is provided which comprises the step of coupling a glycosyl halide with a monosaccharide in the presence of a silver salt in order to form the disaccharide.
