Organocatalytic enantioselective formal synthesis of HRV 3C-protease inhibitor (1R,3S)-thysanone
摘要:
A short and efficient organocatalytic enantioselective formal synthesis of HRV 3C-protease inhibitor (1R,3S)-thysanone is achieved in a nine-step with 98.7% enantiomeric excess, by employing L-proline-catalyzed asymmetric of alpha-aminooxylation of aldehyde and Oxa-Pictet-Spengler cyclization as the key steps.

An efficient organocatalytic route for the preparation of enantioselectivesynthesis of (S)-1-arylpropan-2-ols derivatives, including the key intermediate of antiepileptic agent (−)-talampanel is described. The key steps involved are L-proline-catalyzed asymmetric α-aminooxylation of aldehydes and regioselective tosylation of diols followed by reduction.
