of the adducts gave a variety of potential antimycobacterials with different “spacers” between the imidazole and (hetero)aryl group. The adduct from furfural was rearranged to a cyclopentenone derivative when treated with methanol under acidic conditions. Several target compounds exhibited antimycobacterial activity in vitro (IC90 13 μg/mL for the best inhibitors), but they were not as active as the
设计并合成了 4-取代的 1-(对甲氧基苄基)咪唑,以模拟高效抗分枝杆菌 6-芳基-9-(对甲氧基苄基)嘌呤的部分结构。4-卤代咪唑经过 Pd 催化的交叉偶联以引入(杂)芳基,或者将它们转化为格氏试剂并与(杂)芳醛反应。加合物的进一步转化产生了多种潜在的抗分枝杆菌,在咪唑和(杂)芳基之间具有不同的“间隔基”。当在酸性条件下用甲醇处理时,来自糠醛的加合物重排为环戊烯酮衍生物。几种目标化合物在体外表现出抗分枝杆菌活性(最佳抑制剂的 IC90 为 13 μg/mL),但它们的活性不如之前合成的最有效的嘌呤和嘧啶。
