Platinum-catalyzed selective C-H acylation of 2-aryloxypyridines with Et chlorooxoacetate provided an efficient way of introducing an α-keto ester functional group. The reaction is oxidant-free, additive-free and more significantly free of any decarbonylative side reactions. The reaction tolerated a variety of substituents from strongly electron-donating to strongly electron-withdrawing groups. Double acylation was feasible for 2-phenoxypyridine and its derivatives with only one substituent at the para position. Although the reaction of 2-(2-methylphenoxy)pyridine with Et malonyl chloride did not produce the desired β-keto ester, the reaction with Et succinyl chloride proceeded smoothly to give the γ-keto ester. Et chlorooxoacetate was much more reactive than Et succinyl chloride in this Pt-catalyzed C-H acylation reaction. In the experiment, the researchers used many compounds, for example, 2-Phenoxypyridine (cas: 4783-68-0Related Products of 4783-68-0).
2-Phenoxypyridine (cas: 4783-68-0) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Reduced pyridines, namely tetrahydropyridines, dihydropyridines and piperidines, are found in numerous natural and synthetic compounds. The synthesis and reactivity of these compounds have often been driven by the fact many of these compounds have interesting and unique pharmacological properties. Related Products of 4783-68-0
