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 through hydrogen bonding, are potentially useful as a catalysts in base-catalyzed processes as well as new ligands in metal-based
对映体纯的1,2- dihydroxyhexahydropyrroloisoquinolines的立体控制合成2 - 4和正式合成ENT - 2 - 4报道从d甘露糖和L-酒石酸起始。强的叔胺碱2 - 4个含羟基,能够通过氢键激活电子试剂,如在碱催化的工艺,以及在金属基催化新配体的催化剂可能有用。
