The reactions of thioquinanthrene (1) with sodium alkoxides derived from 23 alcohols followed by S-alkylation gave the title 4-alkoxy-3′-(alkylthio)-3,4′-diquinolinyl sulfides 3 (18.5–91.5%) and, in some cases, 1,4-dihydro-4-oxo-3′-(alkylthio)-3,4′-diquinolinyl sulfides 4a (up to 31.5%). The effect of the solvent applied, counter-cation used and type of the alkyl group of alkoxide ions was then studied
硫代蒽(1)与23种醇衍生的醇钠的反应,然后进行S-烷基化,得到标题4-烷氧基-3'-(烷硫基)-3,4'-二喹啉基硫化物3(18.5–91.5%),在某些情况下,为1,4-二氢-4-氧代-3'-(烷硫基)-3,4'-二喹啉基硫化物4a(最多31.5%)。然后通过竞争反应研究了所用溶剂,所用抗衡阳离子和烷氧基离子烷基类型的影响。有效地将4-烷氧基-3'-(烷硫基)-3,4'-二喹啉基硫化物3转化为约4个烷氧基-和4-(烷硫基)-3-(烷硫基)喹啉(5,6)和一锅还介绍了从硫代蒽(1)和烷醇钠制备4-烷氧基-3-(烷硫基)喹啉5的方法。
