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-di- hydroimidazo-[2,1-b]thiazoles and corresponding thiazines. These are oxidized to give the corresponding pyridyl-substituted imidazo[2,1-blthiazoles and thiazines, which are active as inhibitors of the 5-lipoxygenase pathway of arachidonic acid metabolism.
