effective one-pot Friedländer quinoline synthesis from o-nitroarylcarbaldehydes and ketones or aldehydes was developed and the scope and limitations of the method were examined. The o-nitroarylcarbaldehydes were reduced to o-aminoarylcarbaldehydes with iron in the presence of a catalytic amount of aqueous hydrochloric acid; the amino compounds were then condensed in situ with ketones or aldehydes to form
开发了一种由邻硝基芳基甲醛和酮或醛合成的高效一锅弗里德兰德喹啉,并研究了该方法的范围和局限性。在催化量的盐酸水溶液存在下,用铁将邻硝基芳基甲醛醛还原为邻氨基芳基甲醛醛。然后将氨基化合物与酮或醛原位缩合,分别形成单取代或双取代的喹啉,收率优良至优异(58-100%)。 喹啉-缩合-杂环-醛-酮
