Reaction of 4-chloro-3′-methylthio-3,4′-diquinolinyl sulfides 3, 9b, 9c with a nitrating mixture proceeds via the 3′-methylthio group monooxidation and yields 3′-methylsulfinyl diquinolinyl sulfides 4, 5b, 5c, respectively. Further treatment of 4 with a nitrating mixture followed as C5- and C8-nitration and gives mixture of 5a and 5c. Treatment of 3′-methylsulfinyl quinolines 6 and 7 with hydrochloric
4-氯-3'-甲硫基3,4'-二喹啉基硫化物3、9b ,9c与硝化混合物的反应通过3'-甲硫基单氧化进行,并生成3'-甲基亚磺酰基二喹啉基硫化物4、5b ,5c,分别。用硝化混合物进一步处理4,随后进行C 5-和C 8硝化,得到5a和5c的混合物。用盐酸/碘化钾体系处理3'-甲基亚磺酰基喹啉6和7会导致6和7中的亚砜基还原为硫化物基,生成8在4-甲氧基喹啉6的情况下,4-甲氧基喹啉部分水解成4-喹啉酮部分同时发生。的质子和碳化学位移4和图5a被完全分配以下COSY,HETCOR和INEPT或COLOC研究。
