Oxidative cyclization of 3-isoquinolyl ketone hydrazones afforded the novel tricyclic heteroaromatic [1,2,3]triazolo[1,5-b]isoquinolinium salts. The reactivity of the ring system towards nucleophiles proved to be regioselective. Secondary amines induced r

Introduction of an acyl group at the α-, β-, and γ-positions of pyridine nuclei was accomplished. 2-Trimethylstannyl-pyridine and -quinoline and 1-trimethylstannylisoquinoline directly reacted with various acyl chlorides to give the corresponding 2-pyridyl, 2-quinolyl, and 1-isoquinolyl ketones, respectively.Reaction of 3-trimethylstannylpyridine, -quinoline, and -isoquinoline with acyl chlorides proceeded smoothly under catalysis by PdCl2 or PdCl2(PPh3)2 to afford the corresponding ketones in good yields.Similary, 4-pyridyl, -quinolyl, and -isoquinolyl ketones were prepared from corresponding 4-trimethylstannyl derivatives and acyl chlorides.Keywords--trimethylstannylazine; palladium-catalyzed reaction; acylation; palladium dichloride; dichlorobis(triphenylphosphine)palladium(II)
