Novel 3-acetoacetylaminobenzo[b]furan derivatives with a modified triene system at the 3-position were prepared through acylation of the 3-aminobenzo[b]furans with 5-methylisoxazole-4-carboxylic acid chloride followed by basic cleavage of the isoxazole ring and several of these compounds showed moderate cysteinyl leukotriene receptor 2 antagonistic activity.
通过3-氨基苯并[b]呋喃与5-甲基异恶唑-4-羧酸氯的酰化反应,然后对异恶唑环进行碱性裂解,制备了在3-位具有修饰的三烯系统的新型3-乙酰乙酰氨基苯并[b]呋喃衍生物。这些化合物中的几种显示出中等的半胱氨酰白三烯受体2拮抗活性。
