Abstract A method for the synthesis of 3-substituted quinoline-4-carboxylates by the reaction of 3-morpholino-1-R-prop-2-en-1-ones with isatins in the presence of trimethylchlorosilane in aqueous alcohol has been developed. The possibility of cyclization of 3-benzoyl-6-R-quinoline-4-carboxylates with hydrazine hydrate to form 9-R-4-phenylpyridazino[4,5-c]quinolin-1(2H)-ones has been shown.
摘要 开发了一种通过 3-morpholino-1-R-prop-2-en-1-ones 与靛红在三甲基氯硅烷存在下的乙醇水溶液中反应合成 3-取代喹啉-4-羧酸盐的方法。3-benzoyl-6-R-quinoline-4-carboxylates 与水合肼环化形成 9-R-4-phenylpyridazino[4,5- c ]quinolin-1(2 H )-ones 的可能性已被证实。
