ABSTRACT An efficient method for the synthesis of 3-amino-1H-quinolin-2-one is described. Condensation of o-nitrobenzaldehyde with hippuric acid gave 4-(2-nitrobenzylidene)-2-phenyloxazol-5-one. This compound was reduced to give 4-(2-aminobenzylidene)-2-phenyloxazol-5-one, which upon isomerization with light, cyclization and hydrolysis afforded the desired product.
摘要描述了一种合成 3-amino-1H-quinolin-2-one 的有效方法。邻硝基苯甲醛与马尿酸缩合得到 4-(2-硝基苯亚甲基)-2-苯基恶唑-5-酮。将该化合物还原得到4-(2-氨基苯亚甲基)-2-苯基恶唑-5-酮,其在光下异构化、环化和水解后得到所需产物。
