The synthesis of racemic nitrile (±)-9 was accomplished in four steps and 58% overall yield from the known pyrrolidinone 5. Nitrile (±)-9 was resolved via preparative chiral HPLC to afford optically pure nitriles (+)-9 and (−)-9, from which 3,3-dimethylprolines (+)-1 and (−)-1 and 3,3-dimethylprolinamides (+)-2 and (−)-2 could be accessed in nearly quantitative yield, without loss of optical purity
