A concise and straightforward total synthetic approach towards lycorine-type alkaloid (?)-γ-lycorane has been achieved in 7 steps. The key feature of the route is the employment of a palladium-catalyzed aromatic C[sbnd]H alkylation of unactivated secondary alkyl iodide. The synthetic protocols also involve a palladium-catalyzed deracemization of allylic carbonate, a Johnson-Claisen rearrangement and an iodocyclization.

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.
