An improved synthetic procedure of racemic bicyclo[3.3.1]nonane-2,6-dione has been developed. Employing Baker’s yeast for sweet dough made it possible to kinetically resolve the racemic compound and to isolate enantiomerically pure (+)-bicyclo[3.3.1]nonane-2,6-dione on a large scale. Furthermore, the developed procedure made it possible to produce (-)-bicyclo[3.3.1]nonane-2,6-dione with an enantiomeric excess of 75%.
