Method for preparing optically pure (−)-clausenamide compound |
| abstract |
Disclosed in the present invention is a method for preparing a (−)-clausenamide compound of formula (I), comprising: firstly, catalyzing the asymmetrical epoxidation of trans-cinnamate using a chiral ketone derived from fructose or a hydrate thereof as a catalyst, and then subjecting the product to amidation, oxidation, cyclization and reduction successively to finally obtain the optically pure (−)-clausenamide compound of formula (I). |
