For preparing pseudo-cord-factors, similar in gross structure to.alpha.,.alpha.-trehalose 6,6'-dimycolate,.alpha.-D-glucopyranosyluronic acid,.alpha.-D-glucopyranosiduronic acid and trehalose dicarboxylic acid were synthesized by catalytic oxidation of trehalose. Such simple derivatives as the dimethyl ester and the hexa-O-acetyl diacid chloride are useful for the attachment of lipid substituents to the carbohydrate core to yield the desired pseudo cord-factors.
