A short and efficient totalsynthesis of the alkaloid isosolenopsin and its enantiomer has been achieved. In the key step, a omega-transaminase catalyzed the regioselective mono-amination of the diketone pentadecane-2,6-dione which was obtained in a single step via Grignard reaction. Initial low conversions in the biotransformation could be overcome by optimisation of the reaction conditions employing
