[摘要]:The reaction of 4-chloro-3-quinolinesulfonyl chloride (I) with sodium hydrogen sulfide led to sodium 4-thioxo-1,4-dihydro-3-quinolinesulfinate (II). Compd. II, in reactions with alkyl halides, was monoalkylated to sodium 4-alkylsulfanyl-3-quinolinesulfinates III (R1 = Me, Et, iPr, allyl, Bn) or double alkylated directly to 4-alkylsulfanyl-3-alkanesulfonylquinolines IV (R1 = Me, Et, Bn, etc.; R2 = Me, iPr, allyl, etc.). |
