A simple and efficient 3 - step synthesis of α-dialkylamino -ketones 3 starting from aldehydes and sec.-amines is described. The unsymmetrically aminoketones are obtained as pure regioisomers viareaction of metalated α-aminonitriles 1 with aldehydes, followed by thermal HCN-elimination/tautomerization.
