The present invention relates to a novel process for the preparation of 1-phenyl-3- aminopropane derivative compounds corresponding to the formula (I) and/or its intermediates, and/or its stereo specific isomers or pharmaceutically acceptable salts, hydrates, or solvates thereof.
A catalytic protocol for the enantio- and diastereoselective reduction of α-substituted-β-keto carbonitriles is described. The reaction involves a DKR-ATH process with the simultaneous construction of β-hydroxy carbonitrile scaffolds with two contiguous stereogenic centers. A wide range of α-substituted-β-keto carbonitriles were obtained in high yields (94%–98%) and excellent enantio- and diastereoselectivities
