Abstract
Enantiomerically pure (R)-2-cyclohexen-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 Diels-Alder reaction and Curtius rearrangement.
