Synthesis of the Two Monomethyl Esters of the Disaccharide 4-O-α-D-Galacturonosyl-D-galacturonic Acid and of Precursors for the Preparation of Higher Oligomers Methyl Uronated in Definite Sequences. -Direct coupling of two D-galacturonic acid esters is achieved using thioglycosides such as (VII) and
