The present invention relates to a short enantioselective synthesis of 1-amino aryl tetraline compounds of Formula 1 via nucleophilic enamine catalysis using organocatalyst such as proline. wherein R1 and R2 represent independent of each other hydrogen, (un)substituted or substituted amine; R3 and R4 represent independent of each other hydrogen or halogen.

Kinetic resolution of the N-methyl imines of 3-substituted indanones and 4-substituted tetralones could be accomplished by hydrosilylation with a chiral titanocene catalyst. N-Methyl imines of 4-substituted tetralones were resolved to yield, after hydrolysis of the unreacted starting materials, ketones with high ee's and the amine products with high diastereomeric and enantiomeric purity. The utility of this process was demonstrated in the synthesis of sertraline.
