A method has been developed for the one pot synthesis of 1'-alkyl-1',4'-dihydro-2.3'-biquinolyl-4'-thiones based on the reduction of 1-alkyl-3-(2-quinolyl)quinolinium halides with sodium borohydride and subsequent thiolation. 1'-Alkyl-1',4'-dihydro-2,3'-biquinolyl-4'-ones were obtained in close to quantitative yield by the oxidation of 1'-alkyl-1',4'-dihydro-2,3'-biquinolyl-4'-thiones.How to Cite
