Powerful aldol reactions: Stereoselective Lewis base catalyzed aldolequivalents expediently provided eight of the ten stereocenters required for the synthesis of erythronolide B. Indeed, all eleven stereocenters present in the erythromycin aglycone have been derived directly or indirectly from catalyticasymmetricequivalents of aldol addition reactions (see scheme).
