6-Aryl-2,3-dihydroimidazo[2,1-b]thiazoles and corresponding thiazines act as nucleophiles, either directly or in the form of Grignard reagents, with N-acylpyridinium salts to produce new 6-aryl-5-(N-acyl-1,4-dihydro-4-pyridyl)-2,3-dihydroimidazo-[2,1-b]thiazole s and corresponding thiazines. These are oxidized to give the corresponding pyridyl-substituted imidazo[2,1-b]thiazoles and thiazines, which are active as inhibitors of the 5-lipoxygenase pathway of arachidonic acid metabolism.
6-芳基-2,3-二氢咪唑[2,1-b]噻唑烷和相应的噻嗪作为亲核试剂,直接或以格氏试剂的形式,与N-酰基吡啶盐反应,产生新的6-芳基-5-(N-酰基-1,4-二氢-4-吡啶基)-2,3-二氢咪唑[2,1-b]噻唑烷和相应的噻嗪。这些化合物被氧化,生成相应的吡啶基取代的咪唑[2,1-b]噻唑烷和噻嗪,这些化合物作为花生四烯酸代谢的5-脂氧酶途径的抑制剂具有活性。
