A new synthetic approach directed towards the synthesis of naturallyoccurring 2-alkyl-tetrahydroquinolines is described. The C–C bonds in the α position relative to the nitrogen atom were formed by the reversal of the polarity of the C=N bond of α-amino nitrile 6, which was prepared electrochemically from 1-(phenylethyl)-tetrahydroquinoline. A NaBH4-mediated reductive decyanation process furnished
