C-C - CONNECTIVE SYNTHESIS OF α-DIALKYLAMINO - KETONES FROM ALDEHYDES AND SEC.-AMINES
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 via reaction of metalated α-aminonitriles 1 with aldehydes, followed by thermal HCN-elimination/tautomerization.
