A simple procedure leading to beta-aminomethylketones has been developed. The procedure involves base-catalyzed Michael-type addition of sodium t-butyl acetoacetate to N-Boc imines generated in situ followed by hydrolysis and decarboxylation of the adducts.

β-amino ketone derivatives were synthesized by decarboxylative Mannich reaction of chiral N-tert-butanesulfinyl imines with β-keto acids and were subsequently transformed into cis-2,6-disubstituted piperidin-4-ones through an organocatalyzed condensation with aldehydes. Both enantiomers were accessible from the same precursors by inverting the order in the reaction sequence of the aldehydes involved
