An efficient organocatalytic approach to the enantioslective synthesis of two important piperidine alkaloids, namely (+)-α-conhydrine (98 % ee) and (-)-sedamine (95 % ee), by L -proline-catalysed α-aminooxylation of aldehydes has been developed. The strategy involves an intramolecular cyclization to construct the piperidine core.
