For the preparation of L-iduronic acid, trehalose was converted into a derivative of a novel disaccharide, B-Lidopyranosyl I~-L-idopyranoside, through diastereoselective hydroboration of the 5, 5'-di-eno intermediate. The 6-and 6'-hydroxy groups were then oxidized in two steps to give a disaccharide

The synthesis of four enantiopure hydroxyamidines is amidine was obtained by coupling of an (S)-malic acid derived N-acyliminium ion with Ξ²-naphthol. The other described. One amidine was obtained from (S)-pyroglutamic acid. Its key step involved the addition of phenylmagnesium amidines were obtained
