S N Ar和氯化铝诱导的(杂)芳基化反应合成新型3-(喹唑-2-基)喹啉和作为蛋白酶体抑制剂的生物学评价
摘要:
通过S N Ar反应,由易于制备的4-氯-2-(2-氯喹啉-3-基)喹唑啉和一系列酚和苯硫酚作为亲核试剂,合成了一系列新的3-(喹唑-2-基)-喹啉。AlCl 3介导的C–C键的形成也已成功地用于在一个或两个杂环单元上引入芳基和异芳基取代基。这些方法可以在几个步骤中以高收率有效地合成多取代的3-(喹唑-2-基)喹啉。这些多取代的3-(喹唑-2-基)-喹啉中的一些抑制人20S蛋白酶体。

An efficient and green approach has been developed for the synthesis of 2-substituted 2,3-dihydroquinazolin-4(1H)-ones directly from corresponding substituted aromatic and aliphatic aldehyde and anthranilamide using recyclable polymer supported sulfonic acid catalyst under aqueous conditions. Environmental acceptability, operational simplicity, low cost, excellent functional group compatibility, and
An efficient one pot–three component cyclocondensation in the synthesis of 2-(2-chloroquinolin-3-yl)-2,3-dihydroquinazolin-4(1H)-ones: potential antitumor agents
Montmorillonite K10 efficiently catalyzed a one pot–three component cyclocondensation of isatoic anhydride, NH4OAc and aromatic/heteroaromatic aldehydes under ambient conditions to produce the corresponding 2-substituted-2,3-dihydroquinazolin-4(1H)-ones in good yields. The 2-(2-chloroquinolin-3-yl)-2,3-dihydroquinazolin-4(1H)-ones 3a–d were screened for their antitumor activity against Ehrlich Ascites Carcinoma tumor cells
