A synthesis of novel bis(sulfanediyl)bis(tetrahydropyrimido[4,5-b]quinoline-4,6-diones), linked to aryl, heteroaryl, and spirocyclic-oxindole moieties at position-5, as novel hybrid molecules was reported. 2,2′-(Butane-1,4-diylbis(sulfanediyl))bis(6-aminopyrimidin-4(1H)-one) was utilized as a precursor to our target compounds via a multicomponent reaction with two equivalents of both of the appropriate aldehyde and dimedone. The target compounds were alternatively obtained by bis-(alkylation) of the appropriate 5-aryl-2-thioxohexahydropyrimido[4,5-b]quinoline-4,6-dione with 1,4-dibromobutane in moderate basic medium.
