A general approach for the synthesis of pyrolidine member of sedum alkaloids has been developed by employing proline catalysed sequential α-amination and Horner–Wadsworth–Emmons (HWE) olefination of an aldehyde as the key steps. This method can be extended for the synthesis of various bioactive natural products containing pyrolidine skeleton.
