Total synthesis of 13-demethyllyngbyaloside B, an unnatural analogue of a marine macrolide glycoside lyngbyaloside B, has been achieved. The 14-membered macrocyclic backbone was constructed in a convergent manner via esterification and ring-closing metathesis. The bromodiene side chain was introduced by means of a Stille-type reaction and a subsequent bromodesilylation. Finally, the rhamnopyranose unit was stereoselectively introduced by glycosylation under Schmidt conditions.
