PROCESS FOR PRODUCING PYRIPYROPENE DERIVATIVES
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 thr...

| description | 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. (see formula B1)
La présente invention a pour objet un procédé permettant de produire efficacement un dérivé du pyripyropène ayant des groupes acyloxy en positions 1 et 11 et un groupe hydroxy en position 7. Le procédé comprend une étape dans laquelle les groupes hydroxy en positions 1 et 11 du composé représenté par la formule (B1) sont acylés sélectivement au moyen d'un agent d'acylation en présence ou en l'absence d'une base en un à trois stades. |
