Abstract
AbstractAn 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.
