Synthesis of an enantiomerically pure aminoisoquinocarbazole with antiarrhythmic activity via lipase-catalyzed enantioselective transesterification
摘要:
Enantiomerically pure (R)-2-cydohexen-1-ol 5 was prepared via lipase-catalyzed enantioselective transesterification of 2-substituted cyclohexanol, and stereospecifically converted to (-)-(2-cyclohexenyl)acetic acid 4. Enantiomerically pure aminoisoquinocarbazole 1 (RS-2135) was synthesized stereoselectively from 4, using an intramolecular Dids-Alder reaction and Curtius rearrangement.
