Method for producing Praelputrin A |
| abstract |
The present invention provides a method for selectively producing Praeruptoline A in a high yield. Reaction of cis-4'-acetyl kale lactone with angelic acid in the presence of triflate anhydride and base, or cis-4'-acetyl kale lactone with angelic acid anhydride and triflate scandium catalyst It is a manufacturing method of the praeputrin A made to react in presence of this. As the base, diisopropylethylamine can be preferably used. [Selection figure] None |
