Enzyme assisted enantioselective synthesis of the alkaloid (+)-aloperine
摘要:
The enantioselective synthesis of the lupinine alkaloid (+)-aloperine is described. The synthetic scheme presents three steps that are mediated by enzymes: kinetic resolution, oxidation of a primary alcohol to an aldehyde and oxidation of a secondary alcohol to a ketone.

Concise Total Synthesis of (±)-Aloperine and 6-epi-Aloperine
摘要:
Total synthesis of aloperine and 6-epi-aloperine is reported. The crucial steps of the synthetic strategy are an aza-annulation reaction and an intermolecular Diels-Alder reaction. The synthetic plan proceeds from commercially available piperidine-2-ethanol.
