(ZH) 用于合成喜树碱衍生物的中间体及其制备方法和用途
Abstract
(EN) The invention relates to the technical field of organic compound synthesis, in particular to an intermediate for synthesizing a camptothecin derivative as well as a preparation method and applicationof the intermediate. An intermediate A can be obtained by acylation, bromination and cross coupling reaction of 3-fluoro-4-methylaniline. The intermediate A can be used for preparing an intermediate Bso as to further prepare Exatecan mesylate. The intermediate compound B can be obtained by rearrangement reaction of the intermediate A; Exatecan mesylate can be obtained by subjecting the intermediate compound B to alpha-site acetamido and amino deprotection, condensation reaction and hydrolysis reaction. The method has the advantages of low price of reaction initiators, mild reaction conditionsof each step, simplicity and convenience in operation, high yield and suitability for industrial production.
(ZH) 本发明涉及有机化合物合成技术领域，尤其是涉及一种用于合成喜树碱衍生物的中间体及其制备方法和用途。中间体A可由3‑氟‑4‑甲基苯胺经过酰化、溴代、交叉偶联反应得到。该中间体A可以用于制备中间体B进而制备伊喜替康甲磺酸盐。中间体化合物B可由中间体A经过重排反应得到；伊喜替康甲磺酸盐可由化合物B经过ɑ位上乙酰氨基、氨基脱保护、缩合反应、水解反应得到。本发明的反应起始物价格低廉，各步反应条件温和，操作简便，收率高，适合工业化生产。
