Process for producing pyripyropene derivatives |
| abstract |
The present invention discloses a method for efficiently producing pyripyropene derivatives having an acyloxy group at the 1-position and 11-position and a hydroxyl group at the 7-position. The method comprises the step of selectively acylation of hydroxyl groups at the 1-position and 11-position of the compound represented by formula (B1) with an acylating agent through 1-3 steps in the presence or absence of a base. |
