The important intermediate 2-acetyl-5,8-dimethoxytetralin (8) in the syntheses of anthracycline antitumor drugs is easily prepared in high yield on a large scale. Conversion of 2,4-pentanedione to 3-(2,5-dimethoxybenzyl)-hex-5-en-2-one (9) was carried out in a three-step, one-pot process by C-alkylating it with 2,5-dimethoxybenzyl bromide, then allyl bromide followed by a retro-Claisen condensation
蒽环类抗肿瘤药物合成中的重要中间体 2-乙酰基-5,8-二甲氧基四氢萘 (8) 易于大规模高收率制备。2,4-戊二酮向 3-(2,5-二甲氧基苄基)-hex-5-en-2-one (9) 的转化在三步一锅法中通过用 2 ,5-二甲氧基苄基溴,然后是烯丙基溴,然后是逆克莱森缩合。9 向四氢萘 (8) 的转化首先通过臭氧分解为醛 (10),然后在三氟乙酸 - 丙酮中用三甲基硅烷环化和还原后者。
