stereocontrolled synthesis of enantiopure 1,2-dihydroxyhexahydropyrroloisoquinolines 2–4 and a formal synthesis of ent-2–4 starting from d-mannose and l-tartaric acid is reported. The strong tertiary amine bases 2–4 containing hydroxyl groups, able to activate electrophiles throughhydrogen bonding, are potentially useful as a catalysts in base-catalyzed processes as well as newligands in metal-based
