摘要：
Disclosed is a process for efficiently producing pyripyropene derivatives having acyloxy at the 1-position and 11-position and hydroxyl at the 7-position. The process comprises selectively acylating hydroxyl at the 1-position and 11-position of a compound represented by formula B1 through one to three steps with an acylating agent in the presence or absence of a base.
