The 8-methoxycarbonyloctyl glycosides of α-d-mannopyranose, 2-O-α-mannopyranosyl-α-d-mannopyranose, β-d-galactofuranose, and 3-O-β-d-galactofuranosyl-α-d-mannopyranose were prepared as intermediates for the synthesis of complexes with the general structure mono-(or di-)saccharide-lipid spacer-protein having possible antigenic and immunogenic activity in respect to infection with Trypanosoma cruzi. Tri-O-acetyl-1,2-O-(1-methoxyethylidene) derivatives of d-mannopyranose and d-galactofuranose were treated with alcohols in the presence and absence of mercuric bromide to give orthoesters which rearranged into glycosides.
