  Synthesis of 1-(1,3-dialkyl-2-oxo-2,3-dihydro-1H-imidazo-[4,5-b]pyridin-5-yl)-5-oxopyrrolidine-3-carboxylic acids

  摘要：

  Nitration of 2,3-dihydro-1H-imidazo[4,5-b]pyridin-2-one gave its 5-nitro derivative which was subjected to alkylation with dimethyl sulfate, diethyl sulfate, and benzyl(dimethyl)phenylammonium chloride. The resulting 1,3-dimethyl-, 1,3-diethyl-, and 1,3-dibenzyl-5-nitro-2,3-dihydro-1H-imidazo[4,5-b]pyridin-2-ones were reduced to the corresponding 1,3-dialkyl-5-amino-2,3-dihydro-1H-imidazo[4,5-b]pyridin-2-ones, and the latter reacted with itaconic acid to produce 1-(1,3-dialkyl-2-oxo-2,3-dihydro-1H-imidazo[4,5-b]pyridin-5-yl)-5-oxopyrrolidine-3-carboxylic acids. 1-(2-Oxo-2,3-dihydro-1H-imidazo[4,5-b]pyridin-5-yl)-5-oxopyrrolidine-3-carboxylic acid was obtained by analogous reaction with 5-amino-2,3-dihydro-1H-imidazo[4,5-b]-pyridin-2-one.

  2-Arylimidazo[4,5-b]- and [4,5-c]pyridines have been prepared by treatment of the appropriate 2,3- or 3,4-diaminopyridine with an aromatic carboxylic acid in the presence of polyphosphoric acid. Other derivatives have been prepared by similar cyclisation of diaminopyridines using triethyl orthoformate, urea, thiophosgene and thiourea and the properties of some N-oxides have been investigated. A number

  通过在多磷酸存在下用芳族羧酸处理适当的2,3-或3,4-二氨基吡啶，可以制备2-Arylimidazoazo [4,5- b ]-和[4,5- c ]吡啶。使用原甲酸三乙酯，尿素，硫光气和硫脲，通过二氨基吡啶的类似环化反应，已经制备了其他衍生物，并且已经研究了一些N-氧化物的性质。已经筛选了许多芳基咪唑并吡啶的致突变性。
